1.3 RAID Concepts
RAID Fundamentals
The basic idea of RAID (Redundant Array of Independent Disks) is to combine multiple
inexpensive disk drives into an array of disk drives to obtain performance, capacity and
reliability that exceeds that of a single large drive. The array of drives appears to the
host computer as a single logical drive.
Five types of array architectures, RAID 1 through RAID 5, were originally defined; each
provides disk fault-tolerance with different compromises in features and performance. In
addition to these five redundant array architectures, it has become popular to refer to a
non-redundant array of disk drives as a RAID 0 arrays.
Disk Striping
Fundamental to RAID technology is striping. This is a method of combining multiple
drives into one logical storage unit. Striping partitions the storage space of each drive
into stripes, which can be as small as one sector (512 bytes) or as large as several
megabytes. These stripes are then interleaved in a rotating sequence, so that the
combined space is composed alternately of stripes from each drive. The specific type of
operating environment determines whether large or small stripes should be used.
Most operating systems today support concurrent disk I/O operations across multiple
drives. However, in order to maximize throughput for the disk subsystem, the I/O load
must be balanced across all the drives so that each drive can be kept busy as much as
possible. In a multiple drive system without striping, the disk I/O load is never perfectly
balanced. Some drives will contain data files that are frequently accessed and some
drives will rarely be accessed.
By striping the drives in the array with stripes large enough so that each record falls
entirely within one stripe, most records can be evenly distributed across all drives. This
keeps all drives in the array busy during heavy load situations. This situation allows all
drives to work concurrently on different I/O operations, and thus maximize the number
of simultaneous I/O operations that can be performed by the array.

User’s Manual
SAS / SATA II NAS System
Definition of RAID Levels
RAID 0 is typically defined as a group of striped disk drives without parity or data
redundancy. RAID 0 arrays can be configured with large stripes for multi-user
environments or small stripes for single-user systems that access long sequential records.
RAID 0 arrays deliver the best data storage efficiency and performance of any array type.
The disadvantage is that if one drive in a RAID 0 array fails, the entire array fails.
RAID 1, also known as disk mirroring, is simply a pair of disk drives that store duplicate
data but appear to the computer as a single drive. Although striping is not used within a
single mirrored drive pair, multiple RAID 1 arrays can be striped together to create a
single large array consisting of pairs of mirrored drives. All writes must go to both drives
of a mirrored pair so that the information on the drives is kept identical. However, each
individual drive can perform simultaneous, independent read operations. Mirroring thus
doubles the read performance of a single non-mirrored drive and while the write
performance is unchanged. RAID 1 delivers the best performance of any redundant array
type. In addition, there is less performance degradation during drive failure than in RAID
5 arrays.

SAS / SATA II NAS System
RAID 3 sector-stripes data across groups of drives, but one drive in the group is
dedicated for storing parity information. RAID 3 relies on the embedded ECC in each
sector for error detection. In the case of drive failure, data recovery is accomplished by
calculating the exclusive OR (XOR) of the information recorded on the remaining drives.
Records typically span all drives, which optimizes the disk transfer rate. Because each
I/O request accesses every drive in the array, RAID 3 arrays can satisfy only one I/O
request at a time. RAID 3 delivers the best performance for single-user, single-tasking
environments with long records. Synchronized-spindle drives are required for RAID 3
arrays in order to avoid performance degradation with short records. RAID 5 arrays with
small stripes can yield similar performance to RAID 3 arrays.
Under RAID 5 parity information is distributed across all the drives. Since there is no
dedicated parity drive, all drives contain data and read operations can be overlapped on
every drive in the array. Write operations will typically access one data drive and one
parity drive. However, because different records store their parity on different drives,
write operations can usually be overlapped.
Dual-level RAID achieves a balance between the increased data availability inherent in
RAID 1 and RAID 5 and the increased read performance inherent in disk striping (RAID
0). These arrays are sometimes referred to as RAID 0+1 or RAID 1+0 and RAID 0+5 or
RAID 50.

SAS / SATA II NAS System
RAID 6 is similar to RAID 5 in that data protection is achieved by writing parity
information to the physical drives in the array. With RAID 6, however, two sets of parity
data are used. These two sets are different, and each set occupies a capacity equivalent
to that of one of the constituent drives. The main advantage of RAID 6 is High data
availability – any two drives can fail without loss of critical data.
In summary:
Š
RAID 0 is the fastest and most efficient array type but offers no fault-tolerance. RAID
0 requires a minimum of one drive.
Š
RAID 1 is the best choice for performance-critical, fault-tolerant environments. RAID
1 is the only choice for fault-tolerance if no more than two drives are used.
Š
RAID 3 can be used to speed up data transfer and provide fault-tolerance in singleuser environments that access long sequential records. However, RAID 3 does not
allow overlapping of multiple I/O operations and requires synchronized-spindle drives
to avoid performance degradation with short records. RAID 5 with a small stripe size
offers similar performance.
Š
RAID 5 combines efficient, fault-tolerant data storage with good performance
characteristics. However, write performance and performance during drive failure is
slower than with RAID 1. Rebuild operations also require more time than with RAID 1
because parity information is also reconstructed. At least three drives are required
for RAID 5 arrays.
Š
RAID 6 is essentially an extension of RAID level 5 which allows for additional fault
tolerance by using a second independent distributed parity scheme (two-dimensional
parity). Data is striped on a block level across a set of drives, just like in RAID 5, and
a second set of parity is calculated and written across all the drives; RAID 6 provides
for an extremely high data fault tolerance and can sustain multiple simultaneous
drive failures. It is a perfect solution for mission critical applications.

RAID Management
The subsystem can implement several different levels of RAID technology. RAID levels
supported by the subsystem are shown below.
RAID Level
Description
Min. Drives
0
Block striping is provide, which yields higher
performance than with individual drives. There is
no redundancy.
1
1
Drives are paired and mirrored. All data is 100%
duplicated on an equivalent drive. Fully
redundant.
2
3
Data is striped across several physical drives.
Parity protection is used for data redundancy.
3
5
Data is striped across several physical drives.
Parity protection is used for data redundancy.
3
6
Data is striped across several physical drives.
Parity protection is used for data redundancy.
Requires N+2 drives to implement because of
two-dimensional parity scheme.
4
0+1 (1E)
Combination of RAID levels 0 and 1. This level
provides striping and redundancy through
mirroring. RAID 0+1 requires the use of an even
number of disk drives to achieve data protection,
while RAID 1E (Enhanced Mirroring) uses an odd
number of drives.
4 (3)
30
Combination of RAID levels 0 and 3. This level is
best implemented on two RAID 3 disk arrays
with data striped across both disk arrays.
6
50
RAID 50 provides the features of both RAID 0
and RAID 5. RAID 50 includes both parity and
disk striping across multiple drives. RAID 50 is
best implemented on two RAID 5 disk arrays
with data striped across both disk arrays.
6
60
RAID 60 combines both RAID 6 and RAID 0
features. Data is striped across disks as in RAID
0, and it uses double distributed parity as in
RAID 6. RAID 60 provides data reliability, good
overall performance and supports larger volume
sizes.
RAID 60 also provides very high reliability
because data is still available even if multiple disk
drives fail (two in each disk array).

1.4 Array Definition
1.4.1 Raid Set
A Raid Set is a group of disk drives containing one or more logical volumes called
Volume Sets. It is not possible to have multiple Raid Sets on the same disk drives.
A Volume Set must be created either on an existing Raid Set or on a group of available
individual disk drives (disk drives that are not yet a part of a Raid Set). If there are
existing Raid Sets with available raw capacity, new Volume Set can be created. New
Volume Set can also be created on an existing Raid Set without free raw capacity by
expanding the Raid Set using available disk drive(s) which is/are not yet Raid Set
member. If disk drives of different capacity are grouped together in a Raid Set, then
the capacity of the smallest disk will become the effective capacity of all the disks in
the Raid Set.
1.4.2 Volume Set
A Volume Set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a Volume Set. A Volume Set capacity can consume all
or a portion of the r aw capacity available in a Raid Set. Multiple Volume Sets can
exist on a group of disks in a Raid Set. Additional Volume Sets created in a specified
Raid Set will reside on all the physical disks in the Raid Set. Thus each Volume Set on
the Raid Set will have its data spread evenly across all the disks in the Raid Set.
Volume Sets of different RAID levels may coexist on the same Raid Set.
In the illustration below, Volume 1 can be assigned a RAID 5 level while Volume 0 might
be assigned a RAID 0+1 level.

1.5 High Availability
1.5.4.1 Creating Hot Spares
A hot spare drive is an unused online available drive, which is ready to replace a failed
disk drive. In a RAID level 1, 0+1, 3, 5 or 6 Raid Set, any unused online available drive
installed but not belonging to a Raid Set can be defined as a hot spare drive. Hot spares
permit you to replace failed drives without powering down the system. When the RAID
subsystem detects a drive failure, the system will do automatic and transparent rebuild
using the hot spare drives. The Raid Set will be reconfigured and rebuilt in the
background while the RAID subsystem continues to handle system request. During the
automatic rebuild process, system activity will continue as normal, however, the system
performance and fault tolerance will be affected.
IMPORTANT: The hot spare must have at least the same or more
capacity as the drive it replaces.
1.5.4.2 Hot-Swap Disk Drive Support
The RAID subsystem has built-in protection circuit to support the replacement of
SATA II hard disk drives without having to shut down or reboot the system. The
removable hard drive tray can deliver “hot swappable” fault-tolerant RAID solution at a
price much less than the cost of conventional SCSI hard disk RAID subsystems. This
feature is provided in the RAID subsystem for advance fault tolerant RAID protection and
“online” drive replacement.
1.5.4.3 Hot-Swap Disk Rebuild
The Hot-Swap feature can be used to rebuild Raid Sets with data redundancy such as
RAID level 1, 0+1, 3, 5 and 6. If a hot spare is not available, the failed disk drive must
be replaced with a new disk drive so that the data on the failed drive can be rebuilt. If
a hot spare is available, the rebuild starts automatically when a drive fails. The RAID
subsystem automatically and transparently rebuilds failed drives in the background
with user-definable rebuild rates. The RAID subsystem will automatically continue the
rebuild process if the subsystem is shut down or powered off abnormally during a
reconstruction process.

5.3 Volume Set Function
Volume Set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a Volume Set. A Volume Set capacity can consume all
or a portion of the r aw capacity available in a Raid Set. Multiple
Volume Sets can exist on a group of disks in a Raid Set. Additional Volume Sets
created in a specified Raid Set will reside on all the physical disks in the Raid Set. Thus
each Volume Set on the Raid Set will have its data spread evenly across all the disks in
the Raid Set.
5.3.1 Create Volume Set
The following are the Volume Set features:
1. Volume sets of different RAID levels may coexist on the same Raid Set.
2. Up to 128 Volume Sets in a Raid Set can be created by the RAID controller.
To create Volume Set from a Raid Set, expand the Volume Set Functions in the main
menu and click on the Create Volume Set link. The Select The Raid Set To Create
On It screen will show all existing Raid Sets. Tick on the Raid Set where you want to
create the Volume Set and then click on the Submit button.
The Volume Set setup screen allows user to configure the Volume Name, Capacity,
RAID level, Initialization Mode, Stripe Size, Cache Mode, Tagged Command Queuing, SAS
Port/LUN Base/LUN, and Volume To Be Created.

Volume Name:
The default Volume Set name will appear as “Volume---VOL#XXX”. You can rename
the Volume Set name provided it does not exceed the 16 characters limit.
Raid Level:
Set the RAID level for the Volume Set. Click the down-arrow in the drop-down list. The
available RAID levels for the current Volume Set are displayed. Select the preferred
RAID level.
Capacity:
The maximum Volume Set size is displayed by default. If necessary, change the
Volume Set size appropriate for your application.
Greater Two TB Volume Support:
If the Volume Set size is over 2TB, an option “Greater Two TB Volume Support” will be
automatically provided in the screen as shown in the example above. There are three
options to select: “No”, “64bit LBA”, and “4K Block”).
No: Volume Set size is set to maximum 2TB limitation.
64bit LBA: Use this option for UNIX, Linux, and Windows Server 2003 + SP1 or later
versions. The maximum Volume Set size is up to 512TB.
4K Block: Use this option for Windows OS such as Windows 2000, 2003, or XP.
The maximum Volume Set size is 16TB. Just use the Volume as “Basic Disk”.
Volume can’t be used as “Dynamic Disk”; also can’t be used in 512Bytes block
service program.
NOTE: For NAS system usage, if you want the maximum capacity
allowed to be over 2TB and to have a single Volume Set over 2TB,
select the “64bit LBA” option.
Initialization Mode:
Set the Initialization Mode for the Volume Set. Foreground mode is completed faster
but Volume Set but be completed before it becomes accessible. Background mode makes
the Volume Set available instantly but the initialization process takes longer.
Stripe Size:
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 0+1, 5
or 6 Volume Set. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, or
128 KB.
A larger stripe size produces better-read performance, especially if your computer does
mostly sequential reads. However, if you are sure that your computer does random
reads more often, select a small stripe size.
NOTE Stripe Size in RAID level 3 can’t be modified.

Cache Mode:
The RAID subsystem supports Write-Through Cache and Write-Back Cache.
Write-Through: the RAID controller acknowledges data has been received when it
reaches the disk drives.
Write-Back: the RAID controller acknowledges data has been received when it
reaches the controller’s cache memory. This provides better performance but requires
a battery module support for the cache memory, or a UPS where the system can be
connected.
Tagged Command Queuing:
When this option is enabled, it enhances the overall system performance under multitasking operating systems by reordering tasks or requests in the command queue of
the RAID system. This function should normally remain enabled.
SAS Port/LUN Base/LUN:
SAS Port: There are two 3Gbps SAS Host Channels in the RAID subsystem. Select
the SAS port where to map the LUN (Volume Set). Options are: 0, 1 and 0&1
Cluster. 0&1 Cluster will make the LUN visible on both SAS ports.
LUN Base: T h e b ase LUN number. Each LUN Base supports 8 LUNs.
LUN: Each Volume Set must be assigned a unique LUN ID number. A SAS Port can
connect up to 128 devices (LUN ID: 0 to 127). Select the LUN ID for the
Volume Set.
Volumes To Be Created: Use this option to create several Volume Sets with the same
Volume Set attributes. Up to 128 Volume Sets can be created.

6.2 Upgrading the RAID Controller’s Firmware
Upgrading Firmware Using Flash Programming Utility
Since the RAID subsystem’s controller features flash firmware, it is not necessary to
change the hardware flash chip in order to upgrade the controller firmware. User can
simply re-program the old firmware through the RS-232 port. New releases of the
firmware are available in the form of binary file at vendor’s FTP. The file available at the
FTP site is usually a self-extracting file that contains the following:
XXXXVVV.BIN Firmware Binary (where “XXXX” refers to the model name and
“VVV” refers to the firmware version)
README.TXT It contains the history information of the firmware change. Read this file
first before upgrading the firmware.
These files must be extracted from the compressed file and copied to one directory in the
host computer.
Establishing the Connection for the RS-232
The firmware can be downloaded to the RAID subsystem’s controller using an ANSI/VT100 compatible terminal emulation program or web browser-based RAID Manager
remote management page.
With terminal emulation program, you must complete the appropriate installation and

8.1 Volume Manager
The Volume Manager is responsible for disk and volume management.
A Volume Group consists of one or more disks that could be individual physical disk(s) or
RAID disk(s), which is/are Volume(s) created using proRAID Manager. The default
proNAS Volume Group (proNASVG) must be created first by joining at least one “New” or
“Non_Initialized” disk to this volume group. The proNASVG holds the NAS system
configuration and the default system Logical Volumes, such as home, public, proBackup
Device, and proBackup Extended Device, as well as user-defined Logical Volumes. Files
and folders reside on these Logical Volumes.
The default proNASVG Volume Group cannot be deleted. When proNASVG is created, the
XFS file system is set in each default Logical Volume. XFS file system is also set in all
user-defined Logical Volumes. XFS is a high performance journaling file system and
provides better recovery time to repair a file system in case of FS damage. The proNAS
Volume Group will dynamically allocate some space from its assigned disks, and
allocation may fail if no more disk space is available. Therefore, make sure to regularly
monitor the available free space of proNAS Volume Group.
The Volume Manager can perform the following function:
‹
Create a VG (volume group)
‹
Join New Disks
‹
Reset a VG (volume group)
‹
Remove a VG (volume group)
‹
Create Logical Volume
‹
Create Snapshot
‹

8.1.3 Volume Snapshot
Snapshots are point-in-time copies of a logical volume. This allows the system
administrator to create a new block device which presents an exact copy of a logical
volume, frozen at some point in time. As changes are made to the original volume, the
snapshot remains the same and looks exactly like the original at the time the snapshot
was created.
A Snapshot can be created manually or scheduled. Admin need to enable first this
special function.
NOTE: Logical Volume with snapshot cannot be extended nor
replicated (see next section about Volume Replication).
To enable Snapshot function, select Volume Manager then click Options tab. Tick the
“Enable Snapshot function” option.
NOTE: Creating Snapshots while a Logical Volume is under heavy
I/O will slowdown the I/O access or interrupt the I/O process to a
Logical Volume. This means that clients accessing the proNAS
share, in which the Logical Volume is under snapshot, can
experience slow write access.

8.1.4 Volume Replication
Replication function enables proNAS to replicate a logical volume from one NAS server
(source) to another NAS server (destination). Replication involves intelligent copying and
maintaining of exact copy of a volume from a source server to a destination server. The
destination volume is always an exact copy of the source volume. This is done by
mirroring the whole block device via a standard network interface. This solution creates
a real time replication of data. However, it does not create a cluster solution where you
can have a highly available system.
Note: Logical Volume under snapshot cannot be replicated.
NOTE: In proNAS version 1.3.xx, Replication of Logical Volumes
with LV capacity up to 16TB is supported.
To enable Replication, select Volume Manager then click Options tab and tick “Enable
Replication function”.
NOTE: Make sure the two proNAS servers have different host
names before setting up Replication.
It is advisable to configure a network port, in each of the two NAS
servers, as dedicated channel/medium for Replication.

connection on this medium. As much as possible, set this channel
as a dedicated or a private network. It is recommended to use
different Ethernet port for replication from the Ethernet port used
for data access. It is best to use a crossover network link between
the Ethernet ports involved. Refer to Network Manager Section for

Connection Type: proNAS supports two types of data replication protocols:
Sync - Synchronous. The system will acknowledge the transaction as completed
after the data is written to the disk of destination proNAS. It is recommended to
use this mode. In most cases, this connection type preserves transaction
semantics. Write IO is reported as completed if it has reached the remote disk.
Async (for high latency network) - Asynchronous. The system will acknowledge
the transaction as completed after the data is written to buffer. It provides faster
transmission and is suitable for busy network. Write IO is reported as completed
if it has reached the local TCP send buffer.
Max Sync Rate – This sets the limit of the bandwidth that will be used by the
synchronization process. Default is 30MB/sec. Minimum value is 4MB/sec and
maximum value is 680 MB/sec – for high latency network environment (e.g. bonding
on Gigabit Ethernet).
Send buffer size (K) - It is the size of the TCP socket send buffer. You can specify
smaller or larger values. Larger values are appropriate for reasonable write
throughput with asynchronous protocol over high latency networks. Default is 512K
and maximum is 1024K.
Time out (sec) - It is the value to wait for connection timeout if the remote node is
degraded. If the remote node fails to send the response packet within the specified
timeout time, the remote node will be considered dead and the TCP/IP connection is
abandoned. The default is 6 sec. Minimum is 1 sec and maximum is 60 sec.
When Lost Connection: When the replication connection is lost, the replication
program can either go stand-alone or will try to reconnect.
Reconnect: The replication program will attempt to reconnect. (Default)
Stand-alone: The replication program will not attempt to reconnect and will go
on stand-alone state. All IO request are only passed locally and no replication.
NOTE: Before replication will be successfully created, a 4GB logical

5. Select the LV name, then click Replication tab. Initialize the Replication by clicking
“Initial Replication” button. When the confirmation message is displayed, select
“Yes” to continue.
NOTE: After creating Replication on a logical volume, a similar
logical volume will be created on the destination server under the
specified VG. At this point, the Replication is not yet initialized and
no synchronization. Replication still needs to be initialized. After
selecting “Initial Replication” button, the first node will then
connect to the second node and starts to synchronize.
Synchronization typically takes quite a while especially on larger
logical volumes. After initializing, the source node should be in
"Primary" state and the destination node should be in "Secondary"
state. If this is the state, you have now a working replication.
Initializing should be done in the source volume.

8.1.4.2 Checking the Status of Replication
Primary: The node of source volume. All the writing and reading are done on the
primary node.
Secondary: The node of destination volume. The replicated data on the secondary
node is used for backup only and is not accessible. Only the source data is
accessible during replication.
Unknown: The node fails to establish connection.
UpToDate: The node is updated.
Setting the replicated volume on destination proNAS to be Primary
To set the replicated volume to primary, first you need to set both nodes to
secondary. This can be done by setting the primary to be secondary. After both
nodes becomes secondary/secondary, go to the management GUI of the
destination node. Under the replicated logical volume, press the "Set Primary"
button.
WARNING! The replicated volume on the secondary node must not
be mounted. Please do not attempt to mount it manually.
Setting the primary volume to be secondary
To set the primary volume to be secondary, just press the "Set Secondary"
button on the primary node.
Forcing the synchronization
To manually force the synchronization, press the "Force Sync." button. The data
on the primary node will be forcefully synchronized to the secondary node.
Reconnect when the connection of the peer is lost.
To reconnect the replicated volume, press the "Reconnect" button. At some point
if the replication fails to establish connection to the other node, you may try to
set up a connection thru this button. This button will be enabled only if one of the
node losses connection.
Aborting the replication
To abort or drop the replication, press the "Abort Replication" button. To access
the data on the replicated volume after aborting the replication, you may need to
create a share under destination volume whose share name must be equal to the
share name on the source proNAS.

8.4.3 Protocol Setting
ProNAS supports the following share protocols: CIFS and NFS, which can be set in
Protocol tab when creating the share or when in edit mode.
8.4.3.1 CIFS
‹ Enable CIFS Sharing - This option is used to enable or disable CIFS sharing. By
default, this option is enabled. Windows clients usually use CIFS to connect to this
share. Note that newer versions of Mac OS X also support CIFS share connection
without using AppleTalk.
‹ Case sensitive - This control whether filenames are case sensitive.
‹ Hide files that begins with dot - This option controls whether files starting with
a dot will appear as hidden files.
‹ Maximum Connections - This option limits the number of simultaneous
connections at a certain time. Default value is zero, which means an unlimited
number of connections are possible in this share.
NOTE: The default setting of “Maximum Connections” is 0. If there
is a need to limit the number of simultaneous connections to a
CIFS share, set it to specific number instead of 0.

8.4.3.2 NFS
‹
Enable NFS file sharing v2/v3 - This specifies whether to enable or disable
NFS version 2 / version 3 file sharing. NFS is used in UNIX/Linux environment.
‹
Enable NFS file sharing v4 - This specifies whether to enable or disable NFS
version 4 file sharing.
‹
Synchronize write operation – Use this option to enable or disable write
caching
‹
Allow root's access – Use this option to allow or disallow access by root super
user account
‹
Insecure - If you choose this option, it means only the port under 1024 can
access, it provides higher security
‹
Subtree check – Use this option to enable or disable subtree checking. A subtree
check happens if a subdirectory of a filesystem is exported, but the whole
filesystem isn't then whenever a NFS request arrives, the server must check not
only that the accessed file is in the appropriate filesystem (which is easy) but also
that it is in the exported tree (which is harder).
Accessing proNAS shares under Linux
For NFS share:
Usage:
Where:
mount -t nfs x.x.x.x:/mnt/proNAS/volume/share /mnt/temp
x.x.x.x = proNAS IP address
/mnt/proNAS/volume/share = the complete path of the NFS share. You
may use the command "showmount -e x.x.x.x" to query the complete
path.
/mnt/temp = local mount point on the client
For CIFS share:
Usage:
mount -t smbfs //x.x.x.x/share /mnt/temp -o
username=account,password=secret
or
mount.cifs //x.x.x.x/share /mnt/temp -o
username=account,password=secret
or
smbmount //x.x.x.x/share /mnt/temp -o
username=account,password=secret
where:
x.x.x.x = proNAS IP address
share = CIFS share name. You may use the command "smbclient -L
x.x.x.x" to query the CIFS share names.
/mnt/temp = local client mount point.
-o username=account,password=secret = the account name and
password

8.4.5 Rsync
Rsync copies files either to or from a remote host, or locally on the current host. It is
also a utility that provides fast incremental file transfer. proNAS Rsync implementation
can be set either in server mode or client mode. Server mode means that proNAS can
accept incoming Rsync connections, where as in client mode, proNAS is the one who
initiates the synchronization. To use as a server mode, you must start the "RSYNC
server” first. Go to System Manager -> Service tab, highlight "RSYNC server” then click
the “Start” button.
Some of the additional features of Rsync are:
‹ Support for copying links, devices, owners, groups, and permissions.
‹ Pipelining of file transfers to minimize latency costs
‹ Support for anonymous or authenticated Rsync daemons
174
User’s Manual
SAS / SATA II NAS System
Server Mode:
When proNAS system is in Server Mode, the Rsync clients can connect either within a
local transfer, via a remote shell or via a network socket.
‹ Enable - When checked, proNAS is set as a Rsync server.
‹ Read only - When checked, all files within this share will be read only to any
Rsync client.
‹ Anonymous - When checked, anonymous connections will be accepted.
‹ Maximum Connections - This specifies the maximum number of Rsync client that
can connect to this share at a certain time.
‹ Edit accounts - You may edit and existing account, or add/delete a user. These
accounts are the accounts that need to be supplied by the Rsync clients when
connecting to this server.
User’s Manual
175
SAS / SATA II NAS System
Client Mode:
The proNAS system will initiate the synchronization and contact an Rsync server. There
are two different ways for Rsync to contact a remote system: using SSH as a remoteshell program as the transport or contacting an Rsync daemon directly via TCP.
‹ IP Address - This specifies the IP address of the remote Rsync server.
‹ Remote Path - This specifies the share on the remote Rsync server.
‹ Account - The valid account name that will be required by the Rsync server for
authentication.
‹ Password - The account's password.
‹ Mode - Either to download files from the Rsync server or to upload files into the
Rsync server.
‹ SSH - When checked, SSH service will provide the secure tunnel between an
Rsync client and an Rsync server.
‹ Rsync Options - These are the lists of options used during Rsync file transfer
176
User’s Manual
SAS / SATA II NAS System
Here is a short summary of the available options. Please refer to the detailed description
below for a complete description. Some options only have a long variant.
-r, --recursive
recurse into directories
-v, --verbose
increase verbosity. This option increases the amount of information
your are given during the transfer
-l, --links
copy symlinks as symlinks
-p, --perms
preserve permissions. This option causes the receiving Rsync to set
the destination permissions to be the same as the source permissions.
-o, --owner
preserve owner (super-user only). This option causes Rsync to set the
owner of the destination file to be the same as the source file
-g, --group
preserve group. This option causes Rsync to set the group of the
destination file to be the same as the source file.
--ignore-existing
Ignore files that already exist on the receiver. This tells Rsync to skip
updating files that already exist on the destination.
-b, --backup
With this option, preexisting destination files are renamed as each file
is transferred or deleted. You can control where the backup file goes
and what (if any) suffix gets appended using the --backup-dir and -suffix options
--backup-dir=dir
In combination with the --backup option, this tells Rsync to store all
backups in the specified directory. This is very useful for incremental
backups. You can additionally specify a backup suffix using the -suffix option (otherwise the files backed up in the specified directory
will keep their original filenames).
--suffix=SUFFIX
This option allows you to override the default backup suffix used with
the --backup (-b) option. The default suffix is a ~ if no --backup-dir is
specified, otherwise it is an empty string.
-D, --devices
preserve device files
--specials
preserve special files
-t, --times
preserve times
-S, --sparse
handle sparse files efficiently
-z, --compress
Compresses file data during the transfer. This option is useful in slow
links.
-a, --archive
This is equivalent to -rlptgoD. It is a quick way of saying you want
recursion and want to preserve almost everything (with -H being a
notable omission).
-E, --executability This option causes Rsync to preserve the executability (or nonexecutability) of regular files when --perms is not enabled.
-h, --humanreadable
Output numbers in a human-readable format.
--stats
Give some file-transfer stats.
--delete
Delete files that don't exist on the sender.
--log-fileformat=FORMAT
Output filenames using the specified format.
--log-file=FILE
Output filenames using the specified file.
User’s Manual
177
SAS / SATA II NAS System
--bwlimit=KB/S
Limit I/O bandwidth; KBytes per second.
-n, --dry-run
This tells Rsync to not do any file transfer; instead it will just report
the actions it would have taken.
--timeout=SECS
Sets the maximum I/O timeout in seconds. If no data is transferred
for the specified time then Rsync will exit. The default is 0, which
means no timeout.
There are lot more useful options that are not included in this list. It may vary depending
on your usage, for more information on Rsync, please visit http://samba.org/rsync/.
After completing the above settings, you can run the Rsync client task immediately by
clicking the "Execute" button.

8.4.6 Duplication
Duplication is a file level snapshot utility for making backups of your local filesystem.
Using Duplication, it is possible to take incremental snapshots of your filesystem at
different points in time. Duplication creates the illusion of having a multiple full backups
by using hard links, while only taking up the space of one full backup plus differences.
This saves much more disk space than one might image. The duplication files will be
directed to a share which you can access via share protocols or by telnet service.
Duplication can be invoked manually or by schedule.
Select the share folder in Share Manager then click “Edit” button.
Creating Duplication by Schedule
To create duplication by schedule, first set the number of total duplication that will be
created, specify which day to be run, set the time task whether by interval or once in a
specific time of day, set the destination path and then click “Save” button. Enable the
schedule by clicking on the "Enable Scheduled" button. To disable the scheduled
duplication, just click on the "Disable Scheduled" button.

The Duplication tab information is shown below.
Execute Day:
Specifies whether the scheduled task is to run on this day.
Execute Time:
Once - Specifies the time of the day the scheduled task create
the snapshot.
Every - Specifies how often the scheduled task is to be repeated.
You can also select the starting time and the ending time.
Destination
Path:
This will be the location where your duplication files will be saved.
The default path will be the path of the share itself. You can
change the path to the other shares except home and public.
Duplication will follow the ACL settings of the destination share. If
you set the destination of your home duplication to a public share
then anybody can access that folders, so please be warned!
Snapshot
Numbers:
Specifies the total number of snapshots that can be created. The
maximum total number of duplication a share can have is 256.
NOTE: The destination space must be larger than the source.
proNAS will check only the destination volume size, not the share
usage. Be sure that the available space on the destination is
reasonably big enough to accommodate any changes in the source.
Home duplication is a special case. If the destination path of the
home folder is set to the home itself, its duplication files will only
be accessible via NFS or telnet service.
Create
Duplication:
This button allows you to create duplication
manually.
Delete All:
This button will remove all the duplication files of
this share on the current destination path.

Creating Duplication Manually
To create duplication manually, first set the number of total duplication that will be
created, set the destination path and then click the "CreateDuplication" button. The
source share must have at least a single file in order for the duplication to work properly.
Removing or Clearing All Duplication Files
To delete all the duplication files of this share on the current destination path, press the
"Delete All" button. Duplication files on the previous destination path will not be removed.
Duplication files of other shares on the same destination path will not also be removed.
Getting the Duplication List
To get the lists of all duplication files of this share on the current destination path, please
press the "Get List" button. The table will then update the lists of duplication folders. The
table includes the date and time it was created and the destination path where it was
saved. Duplication files of this share on the previous destination will no longer be
included in the list. However proNAS will automatically update the duplication list for you
every minute.
User’s Manual
181
SAS / SATA II NAS System
How Duplication Works
After you have created Duplication, your destination path will contain a folder
"._Duplication". (It is hidden by default, to unhide it, uncheck the "hide duplication"
option in the Properties tab of the destination folder). Inside the "._Duplication" folder
are the directories that are created for the various intervals that you have defined. It will
look something like in the figure below.
Inside each of these folders is the full backup of that point in time of the source share.
The format of the duplication folder name will be the share name of the source share
appended by an underscore then the character "Dup" followed by the number of the
interval. "ShareName_Dup.0" will always contain the most recent snapshot and the
duplication with the highest interval number will contain the oldest snapshot. When a
new duplication is run, it will rotate all the duplication directories. The files on oldest
duplication will not be saved and will be replaced with the content of its succeeding
duplication, so please take note of this. The number of duplication will depend on the
number of snapshots that you have defined. You need to increase the total number of
snapshots if you want to save the backups for a longer time. For example, if you set the
snapshot numbers to 60 and you set a schedule to take duplication every day, the very
last backup would be around two months old before it will be discharged if a new
duplication is made.
NOTE: To view the date modified of duplication folders that
corresponds to the date the duplication is taken, use File Manager
and view in detailed mode.

proNAS provides 3 kinds of backup methods:
Incremental: An incremental backup stores all files that have changed
since the last backup. The advantage of an incremental backup is that it
takes the least time to complete. However, during a restore operation,
each incremental backup is processed, which could result in a lengthy
restore job.
Differential: A differential backup contains all files that have changed since
the last FULL backup. The advantage of a differential backup is that it
shortens restore time compared to a full backup or an incremental backup.
However, if you perform the differential backup too many times, the size
of the differential backup might grow to be larger than the baseline full
backup.
Full: Full backup

open it, or the browser will prompt users to save the file in the local computer instead.
Upload a file: User needs the write permission of the folder and the file itself. A
browser’s upload window will show up and user needs to locate the file from local
computer to be uploaded to the current directory.
Create a file: User needs the write permission of the folder. A browser’s upload window
will show up and user needs to locate the file in local computer.
Delete a file: User needs the write permission of the folder and the file itself.

Chapter 11 proNAS HA (Optional Function)
11.1 Introduction to proNAS HA
proNAS HA (High Availability) provides solution for business continuity with automatic
failover which ensures that should a critical server become unavailable - due to failure
or maintenance-related downtime — a replica will immediately provide all services in its
place without the need for time-consuming manual procedures.
The core processes of ProNAS HA are implemented as two mutual-guarded fail-safe
proNAS services. They can be manipulated by accessing the Services tab in the proNAS
System Manager node. The dual service architecture of ProNAS HA prevents ProNAS
HA from being the single-point-of-failure of the server cluster.
When a server is down or unavailable, ProNAS HA switches the critical operations of
that server over to the peer server automatically. The switch over procedure can also
be triggered manually to handle scheduled downtime more gracefully and user
transparently. ProNAS HA can be manually instructed to switch over the critical
operations of a server to the peer server. Users can then perform upgrade, replacement,
or maintenance to the hardware and software of that proNAS server. The critical
operations of a server can be configured as auto-switch back. After those critical
operations were taken over by the peer server, ProNAS HA can switch them back to
their original active server when the active server becomes available again. Auto-switch
back ensures that the original load distribution between the two servers will be
resumed immediately when possible.
proNAS HA provides:
¾
¾
¾
Manual or auto-triggered failover to a standby server.
Supports manual or automatic failover back to the original server when ready
Real-time replication minimizes potential data loss
NOTE: proNAS version 1.3.xx supports Replication of Logical
Volumes with LV capacity up to 16TB. proNAS HA also has the
same LV size limit, which means all logical volumes in proNAS
(under HA) must not exceed 16TB.
242
User’s Manual
SAS / SATA II NAS System
11.2 Getting Started with proNAS HA
Before Configuring High Availability
Before attempting to configure two proNAS servers as a High Availability pair,
check the following requirements:
1. Each proNAS server node must have a different and unique hostname. (It
is highly recommended to use the same NAS model.)
2. Each proNAS node must have at least two static IP addresses.
3. Must have a reliable heartbeat, private net Ethernet is required, serial
RS232 is optional.
4. ProNAS HA services must be started in both proNAS servers.
5. The maximum number of logical volumes that can be created under HA is
32.
6. ProNAS HA does not support logical volumes larger than 16TB. Users can
create and extend volumes larger than 16TB but this cannot be used in
proNAS HA.
7. Changing hostname and IP addresses when proNAS HA is running is not
allowed.
8. Snapshot function is disabled under HA.
9. Be sure there are no scheduled snapshot task enabled either on each
proNAS box.
10.ProNAS HA service cannot be started if iSCSI volume exists, Replication is
running, or snapshots exist. Make sure to remove all iSCSI volumes, stop
Replication, or delete snapshots.
Setting up a private network:
Private net is a communication channel between the two proNAS box through which
they exchange information about their states (heartbeats). proNAS supports two
private network, TCP/IP Socket and RS232 Serial Port.
To setup TCP/IP private net: Connect a dedicated network into Ethernet1 adapter. You
may use a crossover cable. Ethernet0 serves as your public net.
To setup RS232 Serial Port private net: Connect a serial cable to either Com1 or Com2
of both proNAS nodes then configure it under the "Serial Port" tab on System Manager.
NOTE: It is recommended to use both TCP/IP and RS-232 for your
private net. Private net IP will be used for replication and RS-232
for heartbeat.
NOTE: You can setup LAN0 Gigabit port (eth0) as your public net;
that is where the users access your proNAS, and also for accessing
proNAS management GUI. Then use LAN1 (eth1) as your Private
Net.

11.2.1 Hardware Aspect
Active server: proNAS HA server that performs cluster-protected operations.
Backup (Standby) server: proNAS HA server that can takeover the critical operations
of an active server when the active server is down or unavailable.
Private net: Private net is a dedicated channel for servers to exchange their operating
status (i.e., heartbeat message).
Types of Private Net Available:
¾
¾
TCP/IP socket: Ethernet network running TCP/IP protocol. Each server must
install a dedicated IP to attach to the private net.
RS-232 serial port: One free serial port per server. A null modem cable must be
installed to connect the serial ports of the two servers.
Public net: Public net is the paths for networked clients to access cluster- protected
resources.

11.2.2 Procedure for Setting Up proNAS HA
Setting up a server cluster:
Below are the basic steps in setting up a server cluster:
1. Configure the hostname for both proNAS servers (must be unique).
2. Configure two static IP addresses for each proNAS server.
3. Set up private net. At least the private net IP must be configured to start cluster.
4. Start proNAS HA service for both proNAS servers. Select System Manager, and
then Services tab, and highlight proNAS HA service then click Start. proNAS HA
node will then appear on the left tree after the service starts successfully.
5. On the designated Active Server, go to proNAS HA->"General Settings".
6. On the "General Setting" tab, click "Edit" button. Input the Peer Server hostname
then select "Active(local-host) – Standby(peer host) Mode" under the
Cluster mode. Click "Save".
NOTE: The Cluster Mode of Backup Server must be configured as
“Standby(local host) – Active(peer-host) Mode” (see Step 10).
Other configuration options:
Computer Name:
Local Server: The hostname of the Active or Primary server
Peer Server: The hostname of the Backup or Secondary server

Reference IP:
Enable Reference IP Checking – Select this option to enable reference
IP checking. A Reference IP is an IP address that the
proNAS HA service will check when the heartbeat channel(s)
between the two servers are lost. This IP will be used as a
reference point to device whether the network really has a
problem before doing failover or takeover. HA will ping the
local and virtual IP address of proNAS, and for any reason
that this fails, HA will ping this reference IP as a double
check. If ping still fails, proNAS HA will proceed with failover
or takeover. The IP of a router or any network device which
is always online can be used as a Reference IP.
IP Address – Enter the IP address of the Reference IP to check the
availability of the servers.
Event Log:
Level – Select the type of logging that will be used for proNAS HA service.
Default is Normal which shows operation processes. Other
option is Trace, which shows operation and traceable
processes.
Preserved Days – Select the number of days that the log will be
preserved before deleting.
Operational Preferences:
On Server Shutdown, failover the resource groups automatically –
When enabled, the resource groups will be failed over to the
other server when this server shutdown.
On Server Startup, start the cluster system automatically – When
enabled, the cluster system will be started automatically
when this server starts up.
