Hi.  I recently had my raid become unresponsive, and had to manually restart
the computer.  When it came back up, evms is telling me that:
MDRaid5RegMgr: Region md/md0 : MD superblocks found in object(s) [sdb
lvm2/container-lvm2-b/region-b ] are not valid.  [sdb
lvm2/container-lvm2-b/region-b ] will not be activated and should be removed
from the region.
and
MDRaid5RegMgr: RAID5 region md/md0 is corrupt.  The number of raid disks for
a full functional array is 8.  The number of active disks is 6.

It seems unlikely that two drives died simultaneously and I assume something
else is going on.  Any thoughts?


Thank you,
Talik
