Expanding a Storage Pool by Adding Disks to a RAID Group

You can add one or more disks to a RAID group in the storage pool.

  • Adding disks to a RAID 1 group changes the RAID type of the group to RAID 5.

  • To expand a RAID 50 or RAID 60 pool, every sub-group must be expanded with the same number of disks.
  1. Go to Main Menu > Storage & Snapshots > Disks/VJBOD.
  2. Verify that the NAS contains one or more free disks.
  3. Go to Main Menu > Storage & Snapshots > Storage/Snapshot.
  4. Verify the following:
    • The storage pool contains at least one RAID 1, RAID 5, or RAID 6 group.

    • The status of the RAID group that you want to expand is Ready.

  5. Select the storage pool that you want to expand.
  6. Click Manage.

    The Storage Pool Management window opens.

  7. Click Expand Pool.

    The Expanding Storage Pool window opens.

  8. Select Add new disk(s) to an existing RAID group.
  9. Select a RAID 1, RAID 5, or RAID 6 group.
  10. Click Next.
  11. Select the disks that will be used to expand the storage pool.
  12. Click Expand.

    A confirmation message appears.


    Clicking OK deletes all data on the selected disks.

  13. Click OK.
  14. Optional: For a RAID 50 or RAID 60 pool, repeat these steps for each sub-group.

QTS starts rebuilding the RAID groups. The capacity of the new disks appears as free space after RAID rebuilding is completed.
