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

Additional Disks Required

Single

RAID 1

One

RAID 1

RAID 5

One or more

RAID 5

RAID 6

One or more
Tip:

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.

  1. Go to Storage & Snapshots > Storage > Storage/Snapshots.
  2. Verify the following:

    • The NAS contains one or more available disks.

    • The capacity of each available disk is greater than or equal to the smallest disk in the RAID group.

  3. Select a storage pool or static volume.
  4. Click Manage.
  5. Select a RAID group.
  6. Select Manage > Migrate RAID Group.
  7. Select one or more disks.
    Warning:

    All data on the selected disks will be deleted.

  8. Click Apply.

    A confirmation message appears.

  9. Click OK.

    The RAID group status changes to Rebuilding....

The RAID type changes to the new type and the RAID group status changes to Ready after migration has finished.
