We strongly recommended copying the RAID volume encryption key to a safe
place. You can find the encryption key file from the USB disk in the following
format:
(RAID volume created date)_xxxxxx.key
WARNING
NOTE
RAID volumes with encryption enabled will be displayed with a key lock
symbol next to volume ID name.
6. Quick RAID — Enabled the quick RAID setting is going to enhance RAID
creation time.
We recommend using the "Quick RAID" setting only if the hard disks are
NOTE
brand new or if no existing partitions are contained.
7. Specify a stripe size — 64K is the default setting.
8. Selected the file system you would like to have for this RAID volume. The
selection is available from ext3, XFS and ext4.
Please keep your USB disk in a safe place and also backup the encrypted
key.
There is no way to rescue data back if the key
is lost.
With RAID volume encryption enabled, the system performance will go
down.
