5. Storage Management
This chapter describes how to create a single-disk volume or a RAID volume. It also outlines the
steps of deleting a volume, expanding a RAID-5 volume and assigning hot-spare disks. After a
volume is created, please refer to the next chapter for more information about sharing data and
assigning permissions.
5.1 Volume Usage and Status
A volume is a logical storage unit. Each volume holds a complete file-system. A volume can exist on a
single disk or a RAID group consisting of two or more disks.
Volume View
List of Volumes
It displays all the volumes in the NAS server. Volume Name shows the volume name which is
defined when creating a volume. Each volume name is also a hyperlink. It opens a page for showing
the detailed information of that volume.
Members indicate the hard disks which compose the volume.
RAID Type indicates whether this volume is JBOD (a single hard disk), RAID 0, RAID 1, RAID 5,
RAID 6 or RAID 10.
Please refer to the next section for more information about RAID.
Free Space indicates the volume usage by showing the free storage space in the volume and the
percentage.
Total Space indicates the volume size.
Status indicates the disk activity on the volume. The disk activity
may be one of the following:
One of the volume members is defective. Data are still intact and
accessible, but the volume is no longer protected by RAID. Data
backup and RAID rebuilding are strongly suggested when a volume is
in this state.
Two of the volume member is defective. Data are still intact and
accessible, but the volume is no longer protected by RAID. Data
backup and RAID rebuilding are strongly suggested when a volume is
in this state
