2.4 RAID VOLUME STATUS
A RAID volume can be in any one of the following statuses.
STATUS MEANING
Good All disks are currently functioning as normal.
Reduced
For RAID levels that provide data protection, one or more disks have failed but the data
is still available via the RAID protection. The failed disk should be replaced as soon as
possible to avoid loss of data.
Rebuilding
A failed disk drive has been replaced and the data is being regenerated on the
replacement disk. When complete, the RAID Group will return to Good status.
Resynchronizing
An error has occurred and the RAID level is being regenerated. When complete, the
RAID Group will return to Good status.
Failed
One or more disks have failed and RAID cannot regenerate the data. The minimum
number of failures required to reach this state depends on the RAID level:
RAID 0, Concatenated, Contiguous: Single disk failure.
RAID 1, 10, and 5: Two disk failure.
