To horizontally expand a Flex-RAID volume:
1. Add disks to the ReadyNAS, if necessary.
For information about how to add a disk to your ReadyNAS system, see the hardware
manual for your system, which is available at
http://www.netgear.com/support/product/ReadyNAS_OS_6.
2. Log in to the Admin Page.
3. Select System > Volumes.
4. Select the volume to expand.
5. Select the unallocated disks to add to the volume.
When you select disks, additional buttons appear on the volume.
6. Select the Expand button.
A Window opens asking you to verify you want to expand the volume.
7. Select the Yes button.
The volume expands immediately, but requires a resync, which starts immediately.
The volume display includes a resync progress bar.
Vertically Expand a Volume
Both X-RAID and Flex-RAID volumes support vertical expansion.
When you vertically expand a Flex-RAID volume, you must replace all disks in the volume
with larger-capacity disks.
Note: Vertical expansion is not available for RAID 0 volumes.
When you vertically expand an X-RAID volume, you must replace disks in the volume
according to the following table.
Table 2. X-RAID vertical expansion requirements
Disk Replacements Required for Vertical ExpansionRAID
Level
Replace 2 or more disks with larger-capacity disks.RAID 1
Replace 2 or more disks with larger-capacity disks.RAID 5
Replace 4 or more disks with larger-capacity disks.RAID 6
If you replace fewer disks than required for vertical expansion, the disks are reserved
for data protection. Your available storage capacity does not increase to accommodate
the reserved disks until you replace the required number of disks.
