In Flex-RAID mode, you assign one of several RAID levels to your volume. Available RAID levels depend on the number of disks that you want the volume to include. For more information, see the What is Flex-RAID and how does it work with my ReadyNAS OS 6 storage system? You can reconfigure your volumes to use a different RAID level.
Note: Changing the RAID level of a volume erases all data. If data is stored on your system, you must back up the data to another storage device before changing the RAID level. You cannot change the RAID level of a RAID 0 volume.
To change to RAID levels:
1. If any data is stored on the volumes that you want to reconfigure, back up your data.
2. Delete the volumes that you want to reconfigure. For more information, see the How do I delete a volume on my ReadyNAS OS 6 storage system?
The disks that were part of the volumes become available again for other purposes (the color of the disks turns black).
3. Create a new volume from the available disks and select the RAID level. For more information, see the How do I create and encrypt a volume on my ReadyNAS OS 6 storage system
The volume is formatted according to your specifications. Formatting can take quite a while, depending on the size of your hard disk drives.
