Use the output to determine whether the FS generation number is in sync and whether the file
serving nodes agree on the ownership of the rejected segments. In the rtool enumseg output,
check the state_flags field for SEGMENT_IN_MIGRATION, which indicates that the segment
is stuck in migration because of a failover.
Typically, if the segment has a healthy state flag on the file serving node that owns the segment
and all file serving nodes agree on the owner of the segment, this is not a file system or file serving
node issue. If a state flag is stale or indicates that a segment is in migration, call HP Support for
a recovery procedure.
Otherwise, the alert indicates a file system generation mismatch. Take the following steps to resolve
this situation:
1.
From the active Fusion Manager, run the following command to propagate a new file system
segment map throughout the cluster. This step takes a few minutes.
ibrix_dbck -I -f
2.
If problems persist, try restarting the client's IAD:
/usr/local/ibrix/init/ibrix_iad restart
