Chapter 2 Getting Started With proNAS 3.6

2.1 Prepare to Setup NAS

1. Before power on, make sure all power cables are plugged.
2. Check that LAN cable is connected to LAN_0 port of NAS and is linked.
3. To initialize the system, at least one hard drive is needed and inserted in the drive slot.

NOTE: Compatible List of Hard Drive Models

NAS product supports major hard drive brands of 2.5-inch and 3.5-inch SAS / SATA hard drive. Please check Unifosa website:

http://www.proware.com.tw for the latest hard disk drives compatibility list for the NAS.

Important Reminder: Unifosa will not be responsible for any data loss due to incorrect installation or use of hard drive and caused damage to the product under abnormal operation.

Warning: When hard drives that have never been used in the NAS are installed, the hard drives will be formatted automatically when Array is created, and existing data on the hard drives will be cleared.

2.2 Login NAS Management Webpage by Using Web Browser

After power on, please wait for about one minute to boot the system, then the NAS can be managed via web browser at any Windows, Linux, or Mac OS client.

1. Open web browser, input http:// in URL bar.

For example: http://172.16.0.1

NOTE:

A. The NAS default IP address is 172.16.0.1.
B. If NAS is set as a DHCP client or you are not sure what IP is used by the NAS, please check the front panel LCD to know the current IP address.
C. Make sure the NAS and the client PC (that you will use to manage the NAS) are on the same subnet.
D. The recommend browsers for management are Google Chrome and Firefox.

1. When the login page (Figure 2.2.1) is shown, input user name "admin" and password (default) "00000000". To select the operating language of the management page, select your preferred language on the drop-down list box on the right side.

NOTE: The default admin password might be different in some NAS. Please ask your NAS vendor if you have problem to logon.

Figure 2.2-1 Login page

1. After login, you will see the main NAS management GUI (Figure 2.3.2-1). You can now start to manage or setup the system.
2. By default, SSL login is enabled in NAS and allows users to configure and manage the NAS via encrypted transmission. To use this function, you can open the browser then input https:// in URL bar.

For example: https://172.16.0.1

NOTE: If the NAS is behind NAT router or firewall and will use SSL login and remote access from the Internet, open NAT or firewall port 443 to direct to the LAN IP of NAS.

2.3 Setup and Installation

All NAS services and functions are disabled without first initializing the NAS. There are two ways to initialize the NAS, by using Quick Initialization feature or manually step by step.

2.3.1 Quick Setup

After login as "admin" and NAS has not been initialized yet, GUI will pop up a message to ask you to use Quick Initialization feature (Figure 2.3.1-1) to setup the system. The Quick Initialization feature helps you to initialize the NAS in just one page setup. To setup using "NAS Quick Initialization", click "Yes". Then you can start to quickly setup the NAS by providing some information and setting some options, as shown in Figure 2.3.1-2.

If you do not want to use Quick Initialization feature, click "No" in Figure 2.3.1-1. Please note that many functions will be disabled without first initializing the NAS. The Options of Quick Initialization page list next page.

Network

Please modify the options here to match your network environment.

Dynamic IP When enabled, this set the NAS as DHCP client (not suggested)

Host Name Set a unique host name for NAS to be used in network environment.

IP address Set a static IP for LAN_0. (Usually for client connection)

Gateway Set gateway IP for LAN_0.

Subnet Mask Set the Subnet Mask for LAN_0.

Array

The NAS must have at least one Array in order to initialize the system.

Array Name It is fixed to "Array01" for the first Array.

Create Spare Enable this option to reserve a hard drive as a spare disk for Array.

Level Select the RAID Level. Quick Initialization only support RAID levels 0,1,5 and 6.

Disk Number The total number of hard drives detected by the system.

Free Size The estimated size of the Array after it is created.

NOTE: All disks will be the member of Array01. If you plan to create the Array manually, please exit (Cancel) the Quick Initialization and read the Chapter 2.3.2.

Logical Volume

Create a network share folder with specified size for users.

Home Size(GB)	The default reserved space for user's home folder
Share Name	The share folder name that will be accessible to users in the network
Share Size(GB)	The volume size of the share folder

Service

Decide which services need to be enabled after setup, and allow users to connect and access the network share folder(s).

Window(Samba)	Select this service to enable access for Window users.
Unix(NFS)	Select this service to enable access for Unix users.
Apple(AFP)	Select this service to enable access for MAC users.

After filling up all options, click "OK" to execute the setup. This only takes about one minute. After setup is completed, you need to re-login the GUI and customize the detailed configuration. Meanwhile, user can access the share folder via network now.

Only one interface in the bond is active. The bond's MAC address is only visible externally on one port (network adapter) to avoid confusing the switch. Active Backup mode provides fault tolerance.	General switches
Balance XOR Balance XOR balances traffic by splitting up outgoing packets between the Ethernet interfaces, using the same one for each specific destination when possible. It transmits based on the selected transmit hash policy. The default policy is a simple slave count operating on Layer 2 where the source MAC address is coupled with destination MAC address. Alternate transmit policies may be selected via the xmit_hash_policy option. Balance XOR mode provides load balancing and fault tolerance.		Supports static trunking. Make sure static trunking is enabled on the switch.
Broadcast Broadcast sends traffic on both network interfaces. This mode provides fault tolerance.		Supports static trunking. Make sure static trunking is enabled on the switch.
IEEE 802.3ad (Dynamic Link Aggregation)	Dynamic Link Aggregation uses a complex algorithm to aggregate adapters by speed and duplex settings. It utilizes all slaves in the active aggregator according to the 802.3ad specification. Dynamic Link Aggregation mode provides load balancing and fault tolerance but requires a switch that supports IEEE 802.3ad with LACP mode properly configured.	Supports 802.3ad LACP
Balance-tlb (Adaptive Transmit Load Balancing)	Balance-tlb uses channel bonding that does not require any special switch. The outgoing traffic is distributed according to the current load on each Ethernet interface (computed relative to the speed). Incoming traffic is received by the current Ethernet interface. If the receiving Ethernet interface fails, the other slave takes over the MAC address of the failed receiving slave. Balance-tlb mode provides load balancing and fault tolerance.	General switches
Balance-alb (Adaptive Load Balancing)	Balance-alb is similar to balance-tlb but also attempts to redistribute incoming (receive load balancing) for IPV4 traffic. This setup does not require any special switch support or configuration. The receive load balancing is achieved by ARP negotiation sent by the localsystem on their way out and overwrites the source hardware address with the unique hardware address of one of the Ethernet interfaces in the bond such that different peers use different hardware address for the server. This mode provides load balancing and fault tolerance.	General switches

Free Size(GB): This displays the selected volume group's unused capacity.
File System: Select the file system format for the LV, default is ext4. Format options are described below.

Format	Description
ext3	This file format is suitable for small I/O, average single-file size of about 4KB-50MB.
ext4	This file format is suitable for big I/O, average single-file size of about 4KB-128MB
xfs	This file format is suitable for big I/O, average single-file size of about 128MB-1GB or above
zfs	This file format is suitable for big I/O, average single-file size of about

128MB-1GB or above, also support compression de-duplication and SSD caching

NOTE: The LV Name only allows up to 32 characters, and can only contain letters, numbers, hyphen (-) and underscore (_).

Size(GB): The size of Logical Volume to be created must be based on the "Free Size (GB)" field, size must be less than the Volume Group available capacity.

Volume Allocation options:

Fixed Size: Create a logical volume with fixed physical size.

Thin Provision: Create a Thin Provisioning pool with Size, and create a Thin Provisioning volume with Allocation Size (option below).

Allocation Size(GB): This field is enabled only when creating LV with Thin Provision. The minimum size of a Thin Provisioning volume is 50GB, and the maximum size is 32TB or 4 times of physical volume size.

Figure 3.5.2-6 Create a Thin Provisioning Logical Volume

Figure 3.5.2-7 Create a ZFS Logical Volume

Compression: This allows tradeoffs between the amount of CPU required for compression and the resulting compression efficiency. Compression also provides increased throughput and performance within the system due to the fact that less data is being written to and read from disk, resulting in fewer I/O operations.

De-duplication: If a file system has the dedup property enabled, duplicate data blocks are removed as they are written to disk. The result is that only unique data is stored on disk and common components are shared between files.

Expanding Logical Volume Capacity:

Select a Logical Volume that need to be expanded in the Logical Volumes List (See Figure 3.5.2-4) and click 'Edit', change the "Logical Volume Size (GB)" to the preferred size, and then click 'Apply'. In Confirm window, select the "Confirm:" option and click 'Yes'. The Logical Volume size will be expanded automatically.

3.8.3 Replication Backup

Replication Backup supports block-level replication of data from one logical volume of a NAS system to another logical volume of another NAS system. The two logical volumes, which are setup with Replication Backup, will be similar to a mirrored logical volume or Raid Level 1, and this enhances the logical volume data protection. When data is written on the source NAS logical volume, the data in the destination NAS logical volume is automatically synchronized. If the source NAS fails, administrator can manually switch and connect directly to the second NAS for continued data access.

Figure 3.8.3-1 Replication Backup List

Add Replication Backup: Click 'Add'. The Add Replication window will be displayed. Set the options below and click 'OK' when done.

Figure 3.8.3-2 Add New Replication Backup

Logic Volume: Select which Volume will be replicated

Interface: Select which NAS Ethernet port will be used for Replication connection Local IP: Displays the local (source) NAS IP address that will be used for Replication.

Remote VG: Enter the VG name on the remote (destination) NAS where the replicated logical volume will be created

Remote IP: Manually enter the remote (destination) NAS IP address that will be used for Replication.

Port: Select a TCP port to bind locally and will be used to connect to the remote NAS.

Buffer Size (KB): 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 2048K.

SyncRate (MB/s): This sets the limit of the bandwidth that will be used by the synchronization process. Default is 30MB/sec. Minimum value is 10MB/sec and maximum value is 1000 MB/sec – for high latency network environment (e.g. bonding on Gigabit Ethernet).

Time Out (Sec): It is the value to wait for connection timeout if the remote NAS has failed. If the remote NAS fails to send the response packet within the specified timeout time, the remote NAS 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

Connection Type: There are two types of Replication Backup Connection:

Sync (Synchronous) - The system will acknowledge the transaction as completed after the data is written to the logical volume of destination NAS. 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 logical volume.

Async (Asynchronous - for high latency network) - The system will acknowledge the transaction as completed after the data is written to system 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.

Lost Connect: When connection is lost, the Replication Backup can either go to stand-alone mode or will try to reconnect.

Reconnect: The Replication Backup will attempt to reconnect. (Default)

Stand-alone: The Replication Backup will not attempt to reconnect and will be in stand-alone state. All IO requests are only passed locally and no replication.

NOTE: Before Replication Backup is successfully created, a 4GB logical volume will be created on each NAS. This will serve as the metadata device for the replicated volume. This volume is not mounted and will not be seen on the NAS GUI. Please be sure to have an extra 4GB available VG space on both source and destination NAS.

Initialize or Edit Replication: Select the Logical Volume name in Replication Backup list, and then click 'Edit'. The Edit Replication window will appear.

Figure 3.8.3-3 Modify Replication Backup

Initial Replication: Click "Initial Replication" to initialize the Replication Backup for the selected Logical Volume.

Figure 3.8.3-4 Replication Backup Status

NOTE: After setup of Replication Backup on a logical volume in source NAS, a similar logical volume will be automatically created on the destination NAS under the specified VG. At this point, the Replication Backup is not yet initialized and no synchronization. Replication Backup still needs to be initialized first. After selecting "Initial Replication" button, the source NAS will then connect to the destination NAS and starts to synchronize. Synchronization typically takes quite a while especially on larger logical volume. After initialization, the source NAS should be in "Primary" state and the destination NAS should be in "Secondary" state. If this is the state, you have now a working Replication Backup. Initializing the Replication is done in the source NAS.

Set Primary: To set the replicated logical volume in destination (Secondary) NAS to be Primary, both NAS must be set first to Secondary state. This can be done by setting the Primary NAS to be Secondary. After both NAS becomes Secondary/Secondary, go to the NAS GUI of the destination NAS. Edit the replicated logical volume and use the "Set Primary" button.

Set Secondary: To set a Primary (source) logical volume to be Secondary (destination), use the "Set Secondary" button on the Primary NAS.

Force Sync: To manually force the synchronization, click the "Force Sync" button. The data on the primary NAS will be forcefully synchronized to the secondary NAS.

Reconnect: To reconnect a broken Replication Backup connection, click the "Reconnect" button. At some point in time, if Replication Backup fails to establish connection to the other NAS, you may try to re-establish connection thru this button. This button will be enabled only if one of the NAS losses connection.

Abort Replication: To abort or drop the replication, click the "Abort Replication" button. After aborting replication, the data on the destination logical volume (Secondary NAS) can be retrieved by accessing the share folder under that destination logical volume, and the share folder name is exactly the same as the share folder on the source logical volume (Primary NAS).

NOTE: Snapshot and Thin Provisioning volumes do not support Replication.

Extending Logical Volume Size under Replication Backup

The following are the steps:

1. Abort the Replication Backup by selecting "Abort Replication" button.
2. Delete the replicated logical volume on the destination (Secondary) NAS.

3. Extend the size of the source logical volume in primary NAS. Please note that there should be enough space on the VG of the destination NAS to accommodate the extended logical volume space. For example, if the size of source logical volume is now 3TB, the VG ("Remote VG") on the destination NAS must also have free 3TB space for creating the replicated logical volume (Note that after aborting replication, the same logical volume name can be deleted on the destination NAS to free up VG space).

4. Create a new Replication Backup using the extended logical volume on primary NAS.

NOTE:

Extending the size of a Logical Volume under Replication Backup is not allowed. However, there is a work around to extend the LV size. Note that the extended LV size must not exceed 16TB.

3.8.4 Snapshot Backup

Snapshot Backup creates a backup "copy" of a logical volume in specific moment in time. This feature is Block Level. Snapshot Backup also supports backup of iSCSI Target Volume and FC Target Volume, including scheduled backup.

Figure 3.8.4-1 Snapshot Backup List

Add Snapshot: Click the 'Add' icon. The Add Snapshot window will appear. Enter the necessary information. Click 'OK' when done.

Figure 3.8.4-2 Create a New Snapshot Backup Plan

Logic Volume: Select the logical volume name that will be used to create Snapshot Backup.

Plan Name: Enter the name of the Snapshot Backup plan. The plan name can be up to 32 characters, and can contain only letters, numbers, hyphen (-), or underscore (_). Space or period (.) is not allowed. Duplicate plan name is also not allowed.

Numbers: This is the maximum number of snapshots. Default is 5. If the maximum number of snapshots is reached, for example there are now 5 snapshot backup, the next/newest snapshot will automatically overwrite the first/oldest snapshot.

Setting Size (GB): This is the capacity that will be used in each snapshot backup. If the amount of data in the logical volume exceeds the capacity that will be used for the snapshot, the snapshot backup will fail and can't be used. In order to avoid such case, it is advisable to set the snapshot capacity (Setting Size) the same as logical volume size.

Logic Volume Type: The system will automatically detect the type of logical volume, such as Default Volume, Logical Volume, Replication Volume, iSCSI Volume, or FC Volume (5 types). This information is for reference only and cannot be changed.

LV Free Size (GB): This is capacity of the selected logical volume. This information is for reference only and cannot be changed.

Volume Group Name: This is the volume group name where the selected logical volume was created. This information is for reference only and cannot be modified.

VG Free Size (GB): This is the free space of the volume group name where the selected logical volume exists. This information is for reference only and cannot be modified.

NOTE: If a logical volume is already used for Snapshot Backup, the logical volume can no longer be used to create another snapshot backup plan. Only one snapshot backup plan is allowed to be created in a logical volume.

Edit Snapshot: Select the Snapshot Backup plan name you want to edit and click the 'Edit' icon. The Edit Snapshot window will appear. Only the "Numbers" and "Setting Size (GB)" can be modified. Click 'OK' when done. The changes will be updated to the snapshot backup plan.

Delete Snapshot Backup Plan: Click the delete icon 📋 on the right of the snapshot backup plan name to be deleted. The Confirm window will appear. Select the 'Yes' button to confirm deletion.

NOTE: Only snapshot backups of logical volumes can be restored. Snapshot backups of iSCSI volumes or FC volumes cannot be restored. However, there is a work around in order to access the data from snapshot backup, and that is to create an iSCSI or FC target volume using the snapshot backup volume (of the iSCSI volume or FC volume), and then connect the client computer to the iSCSI or FC target volume.

Select "Select File Restore" to restore specific files or folders only and click 'OK'. The Confirm window will appear (Figure 3.8.4-7). Click 'Yes'. The Restore Snapshot window will appear (Figure 3.8.4-8). Select the folder or file you want to be restored, choose the Destination folder and click 'Restore'. Data will be restored to the Destination folder.

3.10.1 NAS HA

What's NAS HA?

NAS HA (High Availability) cluster provides solution for business continuity with real time, continuous data replication and synchronization, which ensures that if ever one NAS server/node becomes unavailable, due to failure or maintenance-related downtime, the remaining NAS server/node can still provide all services to client computers.

NAS HA can have 2-node HA cluster or 3-node HA cluster. All nodes in HA cluster are active. This means in a 2-node HA cluster, for example NAS-1 and NAS-2, resources from each node, such as NAS share folders, are accessible in both nodes. In 3-node HA cluster, all 3-nodes resources are also accessible in all 3 nodes.

Figure 3.10.1-2 Three-nodes HA Cluster

In 3-node HA cluster, Logical Volumes in NAS-1 are replicated to NAS-2, Logical Volumes of NAS-2 are replicated to NAS-3, and Logical Volumes of NAS-3 are replicated to NAS-1.

NAS HA Setup Steps:

Configure NAS Host Names → Configure Network Settings → Configure Logical Volumes and Share Folders → Install NAS HA Plug-in → Setup HA and Start HA Service

NOTE: The VG (Volume Group, such as VG01) in each NAS nodes must have enough VG free space for other NAS node to replicate Logical Volumes. Check the size of Logical Volumes from each NAS node.

1. Configure NAS Host Names

In System Manager -> General -> GUI -> Host Name, change NAS host name.

Figure 3.10.1-3 NAS Host Name

NOTE: The Host Name of NAS nodes cannot be the same, i.e., each NAS Host Name must be unique.

2. Configure Network Settings

In System Manager -> Network, configure LAN_0 and LAN_1 (default LAN ports).

NAS HA service needs 2 LAN interfaces:

Public IP - for NAS configuration, also for client access

Private IP – for HA replication and heartbeat

Figure 3.10.3-4 Configure Network Settings

Please see Section 3.4.2 Network for more information to configure IP address.

3. Configure Logical Volumes and Share Folders

Each NAS node requires least one Logical Volume to run HA.

In NAS GUI of one NAS node, go to Storage Manager -> Volume Group -> VG name (example: VG01), create Logical Volume, for example "LV_1". In Storage Manager -> Share, create share folder under the Logical Volume, for example "share01". In the other NAS node, create different Logical Volume name and Share Folder name.

Figure 3.10.1-5 Add Logical Volume

Please refer to Chapter 3.5 Storage Manager for more information to configure LV and Share Folder.

NOTE: The Logical Volume names and Share Folder names can't be the same between nodes. For example, if NAS-1 has Logical Volume LV_1, then LV_1 must not exist in other NAS nodes, such as in NAS-2, or in NAS-3 (in case of 3-node HA cluster). If Share Folder "share01" is created in NAS-1, other NAS nodes cannot use same share folder name.

NOTE: When creating Logical Volumes, need to consider the size of the Logical Volume and the VG free space on the other NAS node. For example, in 2-node HA, NAS-1 has 5TB LV_1, and NAS-2 has 10TB LV_2. NAS-1 VG must have 10TB free space for LV_2 to replicate, and NAS-2 VG must have 5TB free space for LV_1 to replicate.

4. Install NAS HA Plug-In

When using NAS HA Cluster service, you need to install NAS HA Plug-in in each NAS node that will be included in cluster.

NOTE: If Logical Volumes is not yet finished synchronizing to other NAS node and one NAS node fails, the HA Fail-Over function will not work properly.

i. When synchronization is complete, status will show "active". HA service is working properly.

Figure 3.10.1-23 HA Cluster Status is Active

NOTE: When NAS nodes status show "active", it means HA is working. One NAS node can fail and the other NAS node can still provide the resources from failing NAS node after fail-over.

HA Fail-Over

When one NAS node becomes unavailable, due to some problem such as hardware failure, there is about 5 minutes fail-over time for the Virtual IP of failing NAS node. After about 5 minutes, the remaining NAS node will have taken over, and the Virtual IP of the failing NAS node will become accessible again.

Fail-Over Scenario

When one NAS node fails, the other NAS node will take over. In the example below with 3-node HA cluster, when server A fails, after fail-over to server B, the resources (i.e. Logical Volumes and share folders) from server A will be accessible again from server B. Connect/access using the same Virtual IP of server A.

Testing HA Fail-Over

HA Fail-Over can be tested by:

1. Shutdown one NAS node
2. Power off one NAS node
3. Remove LAN cables from one NAS node

3.11 File Manager

File Manager is a web-based tool used to manage files and folders under a share. The service is enabled by default. It can be disabled in Service Manager. If File Manager service is enabled, all NAS users can logon NAS GUI via web browser and use File Manager for quick maintenance of files (Figure 3.11-1). By default, if admin login NAS GUI, he will be shown with the NAS management GUI. If admin wants to switch to File Manager, click the small File Manager icon on the upper right side, on the right side of "System Log" icon (Chap 3.2).

In the File Manager, all functions are listed in right top menu. File Manager allows NAS users to do file editing like upload(Figure 3.11-8), download, delete(Figure 3.11-3), rename(Figure 3.11-4), copy (Figure 3.11-6) or move(Figure 3.11-7). Just need to make sure the NAS user have read and write permission.
