Can add more disks on my Qnap. Migrating from a single disk to RAID1 (mirror) and from RAID1 to RAID5?
Changing the RAID Type of a RAID Group
You can change the RAID type of an existing RAID group online, without losing access to data or any interruption to NAS services. Changing the RAID type of a RAID group is called RAID migration. QTS allows the following migrations:
|
Original RAID Type |
New RAID Type |
Extra Disks Required |
|---|---|---|
|
Single |
RAID 1 |
One |
|
RAID 1 |
RAID 5 |
One or more |
|
RAID 5 |
RAID 6 |
One or more |
Migration from a single disk to RAID 6 is performed in stages. First migrate the group to RAID 1, then to RAID 5, and then finally to RAID 6.
The RAID type changes and then the RAID group status changes back to Ready when migration is completed.
Then you can migrate to RAID5 and RAID6 if you repeat the process and choose a new RAID option.
