2-14 Managing Your ReadyNAS 2100
v1.1, June 2009
• X-RAID2:
– One-volume technology, but supports volume expansion, either with the addition of more
disks or the replacement of existing disks with larger capacity disks.
– You can start out with one disk, and add more disks as you need them or can afford them.
– Volume management is automatic. Add a second disk, and it becomes a mirror to the first.
Add a third disk and your capacity doubles; add a fourth, and your capacity triples—the
expansion occurring while redundancy is maintained.
– In the future, you will be able to replace disks, one at a time, have each one finish
rebuilding and, after new redundant space becomes available, your volume will
automatically expand to utilize the new capacity.
Volume Management for Flex-RAID
If you want to reconfigure the default Flex-RAID volume C, split it into multiple volumes, specify
a different RAID level, or specify a larger reserved space for snapshots, you need to reconfigure
your volume. The first step is to delete the existing volume you want to replace.
Deleting a Volume
To delete a volume, select the Volume tab of the volume you wish to delete (if there are multiple
volumes) and click Delete Volume (in this case only Volume C is configured).
Warning: Make sure that you back up the files you wish to keep before deleting a
volume. All shares, files, and snapshots residing on that volume will be
deleted and are non-recoverable!
