RAID Recovery
The QNAP NAS supports recovery of a failed RAID group from unintentional disconnection
or removal of the hard drives from the system. Users can recover an inactive RAID 1,
RAID 5, or RAID 6 group to degraded mode, or an inactive RAID 0 and JBOD configuration
to normal.

Follow the steps below to recover an inactive RAID group on the NAS:
1.
Make sure the volume status of the RAID group is “Not active”.
2.
Install the same hard drives, which have been formerly removed from the NAS, back
to the same hard drive slots.
3.
Go to “Storage Manager” > “Storage Pools”. Select the degraded or inactive RAID
group. Click “Manage” > “Recover”.
4.
Wait for about 1 minute for the process to complete. When finished, the NAS data
can be accessed.
Note:
•
After recovering a RAID 1, RAID 5, or RAID 6 RAID group from “not active” to degraded
mode by RAID recovery, users can read or write the volume normally. The volume
status will be recovered to normal after synchronization.
•
If the disconnected drive member is damaged, the RAID recovery function will not
work.
