>Description:
Currently, if multiple components in a RAID device fail such that
the RAID device can no longer reliably continue operation (e.g.,
in a RAID-5 with one parity disk, two components fail), RAIDframe
panics the system. This allows some hope of recovery if the second
component did not fail due to a permenent hardware error. However,
there's no need to go quite so far; simply deconfiguring that
RAID device (thus forcably unmounting the filesystem) would also
do the trick quite nicely, and leave the system up if it were a
non-critical RAID device that failed.
