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

Extra 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 Main Menu > Storage & Snapshots > Storage/Snapshot.
  2. Verify the following:
    • The NAS contains one or more available disks.

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

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

    All data on the selected disks will be deleted.

    A confirmation message appears.

  9. Click OK.

    The RAID group status changes to Migrating.

The RAID type changes and then the RAID group status changes back to Ready when migration is completed.
