Manage Volume
LABEL DESCRIPTION
Repair RAID Select this to repair a degraded RAID volume.
Expand the
volume by
adding disk(s) Select this to add one or more disks to a JBOD, RAID 1 or RAID 5 volume. You can add a
disk to increase an array’s capacity or to use as a hot-spare (standby). When you add a
disk to an existing array, you do not have to re-create shares, access rights and so on as
you would if you create a new volume.
Note: This option is available when a disk has not been allocated to any volume or disk group
yet.
Expand the
volume with
unallocated disk
space Select this to add more storage space to a volume if there is still some space unallocated on
the same disk group. Select this if the NAS fails to expand a volume by adding disk(s) and
the final volume capacity is not as expected. For example, you want to expand a 1 TB RAID
1 volume by adding two more 1 TB disks. The volume size should be 2 TB after expansion,
however, you just see 1 TB. Use this option to fix the issue.
Change RAID
Type Select this if you want to change the volume’s RAID type from Basic to RAID 1, RAID 1 to
RAID 5, or RAID 5 to RAID 6.
