Chapter 4 Web Configurator Basics The following table describes the labels in this screen. Table 12 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.
