Expanding a Single Static Volume by Adding Disks to a RAID Group

The total storage capacity of a single static volume can be expanded by adding one or more additional disks to a RAID group in the static volume. This extra capacity can be added online, without any interruption to data access.

Important:

  • 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 > Storage/Snapshot.
  2. Verify the following:

    • The NAS contains one or more free disks.

    • The storage pool contains at least one RAID 1, RAID 5, or RAID 6 group.

    • The status of the RAID group that will be expanded is Ready.

  3. Select the single static volume that you want to expand.
  4. Click Manage.

    The Volume Management window opens.

  5. Click Expand Volume.

    The Volume Resizing Wizard window opens.

  6. Select Add new disk(s) to an existing RAID group.
  7. Select a RAID 1, RAID 5 or RAID 6 group.
  8. Click Next.
  9. Select one or more disks.
  10. Click Next.
  11. Click Expand.
    Warning:

    All data on the selected disks will be deleted.

    A confirmation message appears.

  12. Click OK.
  13. Optional: For a RAID 50 or RAID 60 volume, 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.
