ReadyNAS OS 6.1
For more information about how to add a disk to your system, see the hardware manual
for your system, which is available at
http://support.netgear.com/product/ReadyNAS-OS6.
Note: You must use supported disks in your ReadyNAS system. For a list
of supported disks, visit http://www.netgear.com/readynas-hcl.
2. Wait for the volume to resync your data.
You can continue to use your ReadyNAS system while the volume is resyncing.
Resyncing can take several hours. The start and completion of the resyncing process is
recorded in the system log (see
System Logs on page 219).
If you set up email notifications for your system, you receive an email message when the
process finishes. For more information about alert notifications, see
Configure System
Alerts on page 169.
3. Repeat Step 1-Step 2 until you have replaced each disk in the volume with a larger-capacity
disk.
Add Protection to a Volume
This section discusses protection against disk failure. The types of protection available
depend on the number of hard disks installed in the ReadyNAS system.
Add Protection to an X-RAID2 Volume
X-RAID2 requires a minimum of two hard disks to provide protection against disk failure. If
you have a one-disk ReadyNAS storage system and want protection from disk failure, you
must add a second disk that is at least as large as the first. You can add it while the system is
running. For more information about how to add a disk to your system, see the hardware
manual for your system, which is available at
http://support.netgear.com/product/ReadyNAS-OS6.
An X-RAID2 volume that includes two or more disks is automatically formatted to protect
against the failure of one disk. If you want to protect your data against the failure of two disks,
you must switch to Flex-RAID and select RAID 6. To use RAID 6, you must install four or
more disks. For more information about how to switch to Flex-RAID, see
Change from
X-RAID2 to Flex-RAID on page 23.
Add Protection to a Flex-RAID Volume
In certain cases, you can add a disk to a Flex-RAID volume to increase data protection. The
following table indicates whether adding a disk for data protection is possible for each
Flex-RAID configuration.
