7. Please note that all data on the selected hard disk drive(s) will be erased. Click "OK"
if you are certain about this.
8. The chosen storage pool will be expanded.
Note: New disks cannot be inserted into existing RAID groups of storage pools for
specific RAID types (such as RAID 0, RAID 10, Single or JBOD). You must create an
additional RAID group to expand those storage pools.
Expanding storage pools by creating new RAID groups
Follow these steps to create a RAID group for storage pool expansion:
1. Go to "Storage Manager" > "STORAGE" > "Storage Space".
2. Double click a storage pool to be expanded to bring up the Storage Pool
Management page.
3. Click "Expand Pool", select "Create and add a new RAID group" and click "Next".
4. Select the enclosure unit, hard disk drive(s), RAID type and hot spare disk and click
"Next".
5. Please note that if the type of the newly-created RAID group is different from that
of the existing RAID group(s), the performance of the entire storage pool may be
affected. To continue, click "OK".
6. Click "Expand".
7. Please note that all data on the selected hard drive(s) will be erased. Click "OK" if
you are certain about this.
8. The chosen storage pool will be expanded.
Note:
RAID 0, JBOD or Single RAID Group cannot be added to a storage pool if that
storage pool already contains RAID 1, 5, 6, or 10.
It is recommended to set an independent storage pool on a JBOD and only add
new disks to that JBOD (or replace the existing disks in that JBOD) when
expanding the storage pool. Otherwise, data stored on that JBOD will become
inaccessible when connecting that JBOD to a different NAS host.
Expanding storage pools by replacing hard disk drives in a RAID array
With this function, RAID group capacity can be expanded by replacing hard disk drives
in an array one by one. This option is supported for the following RAID types: RAID 1,
RAID 5, RAID 6 and RAID 10. Follow these steps to expand a RAID group:
1. Go to "Storage Manager" > "STORAGE" > "Storage Space".
