RAID Recovery

The CELVIN NAS supports exclusive RAID recovery technology to recover a failed RAID disk
volume from unintentional disconnection or removal of the hard drives from the system. Using the
RAID recovery, users can recover an inactive RAID 1, RAID 5, or RAID 6 volume to degraded mode,
or an inactive RAID 0 and JBOD configuration to normal.
