CORRUPT. The partition is not valid. You will need to resilver the partition. This step
copies the membership data from a valid membership partition to the corrupted
partition.
NOTE:
The membership partition may have become corrupt because it was used by another
application. Before resilvering, verify that it is okay to overwrite any existing data
on the partition.
RESILVER. The membership partition is valid but its MP list does not match the servers
local MP list. You will need to determine which membership partitions are correct
(the partitions specified in the local MP list, or the partition labeled RESILVER) and
then resilver accordingly.
CID_MISMATCH. The Cluster-ID is out-of-sync among the membership partitions and
must be reset. See Reset the Cluster ID.
Active and inactive membership partitions
A membership partition can be either active or inactive. (This attribute is reported in
the last field of the record displayed by the mprepair --get_current_mps
command.) The current membership partitions should all be active. If there are old
membership partitions in the cluster, you may want to either remove them or mark
them as inactive.
A cluster could have an old membership partition if the disk containing it becomes
inaccessible and you then add another partition in its place. When the disk access
problem is corrected, the old membership partition will still be on the disk and will
be marked active.
When a membership partition is active, the disk containing the partition cannot be
imported into the cluster. You may see this situation if you want to import a disk that
was previously used by another cluster.
To fix this problem, use the --inactivate_mp option (described under mprepair
Options below) to change the state of the membership partition to inactive. You
can then import the disk into the cluster.
