It may take a lot of time to move a vast number of small files or a single large data file, especially in a slow network environment. JBOD migration function on the QNAP NAS provides a secure and convenient way to move your data to other NAS devices via compatible expansion enclosures.
QNAP expansion enclosures are capable of fast data transmission with high-speed mini SAS cables. Connect expansion enclosures to the QNAP NAS for data backup and then transfer the archived data to other NAS devices. Please refer to the following procedure for JBOD migration.
- Connect an expansion enclosure to the NAS
- Remove the expansion enclosure from the NAS
- Recover the filesystem on the expansion enclosure
Connect an expansion enclosure to the NAS
Note: The destination NAS must also support the same expansion enclosure models with the same type of connectors (e.g. SAS or USB).
Create a new storage pool and volume
(1) Go to “Storage Manager” > “Storage Space”, click “Create”, and then select “New Storage Pool” to bring up the Create Storage Pool screen.
(2) Select the enclosure unit, hard disk drive(s), RAID Type and Hot Spare Disk, and then click "Create”.
(3) Please note that all data on the selected hard disk drive(s) will be erased. Click "OK" if you are certain about this.
(4) A new storage pool is created.
(5) To create a volume for the storage pool, click “Create”, and then select “New Volume” to bring up the Volume Creation Wizard.
(6) Follow the on-screen instructions to create a new volume.
(7) You can use File Station to manually copy desired files to the expansion enclosure.
(1) Go to “Storage Manager” > “Disks”, and then select the enclosure unit (it shows REXP#1 in this example) from the list.
(2) Click “Action”, select “Safely Detach”, and then select “Apply” when a confirmation screen appears to safely detach the expansion unit from the system.
(3) The storage configuration will be preserved along with the unit. You can now disconnect the expansion unit from the NAS.
(1) Connect the expansion enclosure to the destination NAS.
(2) Please wait while the system detects the expansion unit.
Note: To avoid data corruption, do not perform system configurations on the expansion enclosure at this time.
(3) Go to “Storage Manager” > “Disks”, and then select the enclosure unit from the list.
(4) Click “Recover”, and then select “Scan All Free Drives” to recover the filesystem on the expansion enclosure.
(5) After the filesystem is recovered, it is displayed in the Storage Space.
