Expanding a Single Static Volume By Adding a New RAID Group

A new RAID group is created and appended to the single static volume. The total capacity of this new RAID group is then appears as additional storage pool free space.

Warning:
  • If a storage pool contains multiple RAID groups and one RAID group fails, all data in the storage pool will be lost. Ensure that you have a complete data backup plan.

  • To expand a RAID 50 or RAID 60 pool, you must create a new RAID 50 or 60 group with the same number of disks and sub-groups as the original pool. It is not possible to just add additional sub-groups.

QTS writes data to a single static volume that contains multiple RAID groups in a linear manner. This means that QTS writes data to a RAID group until is it full before it writes data to the next RAID group.

  1. Go to Main Menu > Storage & Snapshots > Storage/Snapshot.
  2. Select the single static volume that you want to expand.
  3. Click Manage.

    The Volume Management window opens.

  4. Click Expand Volume.

    The Expanding Volume Wizard window opens.

  5. Select Create and add a new RAID group.
  6. Click Next.
  7. Optional: If you want to use disks in a connected expansion unit, select the expansion unit from the Enclosure Unit list.
    Warning:

    If the selected expansion unit is disconnected from the NAS, all data on the volume will become inaccessible.

  8. Select one or more disks.
    Important:

    For RAID 50 or RAID 60 volumes, the number of selected disks must be equal to or greater than the number of disks initially used to create the volume.

  9. Select a RAID type.
    Important:

    For RAID 50 or RAID 60 you cannot select a different RAID type.

  10. Optional: Select the disk that will be used as the hot spare for this RAID group.
    Note:

    For details, see Configuring a RAID Group Hot Spare

  11. Click Next.
  12. Click Expand.
    Warning:

    All data on the selected disks will be deleted.

    A confirmation message appears.

  13. Click OK.

    QTS creates the new RAID group, and the RAID group starts rebuilding. The volumes status changes to Rebuilding...

After expansion is complete, the volume status changes back to Ready.
