To add a volume:
1. Select the disks. The example shows that the first three disks are selected, and none of
them are specified as a hot spare.
2. Select the RAID level. This will determine how the redundancy, capacity utilization, and
performance are implemented for the volume. Typically in a configuration of three or more
disks, NETGEAR recommends RAID level 5. In the example, RAID level 5 is selected for
the disks.
3. Specify the reserve space for a snapshot. Next, select the percentage of the volume you
want to allocate for snapshots. You can specify 0 if you want to disable snapshot capability,
or you can specify a percentage in 5 percent increments from 5 to 50 percent.
The percentage represents the amount of data you think changes while the snapshot is
active. This typically depends on how often you schedule your snapshot to occur, and the
maximum amount of data (plus padding) you think changes during that time. Make sure
to allocate enough space for a worst case as the snapshot becomes unusable when its
reserved space runs out. In the example, 10 percent of the volume will be reserved for
snapshots.
If you do not reserve space for snapshots, the snapshot screen is not displayed in the
Volume screen.
4. Specify the volume size. After you specify the volume parameters, enter the appropriate
volume size if you want to configure a smaller volume size than the maximum displayed.
The resulting volume will be approximately the size that is specified.
5. Click Apply, and wait for the instruction to reboot the system. It typically takes about 1
minute before you are notified to reboot.
After you reboot, an email notification is sent when the volume has been added. Use the
RAIDar utility to reconnect to the ReadyNAS device.
RAID Settings
After a volume is added, return to the Volume screen and click the RAID Settings screen to
display the current RAID information and configuration options for the volume.
Notice that the disk on Channel 4 that was not configured in the example is listed in the
Available Disks section. To add this disk as a hot spare click Make hot spare.
