Last modified date: 2020-10-23

Applied models:

All NAS Series

Applied Firmware:

All versions

Once the RAID group is configured, it is not possible to reduce the number of disks in it (outside of spare disks).

If you want to remove one or more disks, you may:

Backup data outside of the RAID
Remove the volume and storage pool
Configure a new storage pool/volume with less disks
Copy the data back to the new volume.
