[Lustre-discuss] MDT was remounted to read-only after MDS relocation

Hi,
Our customer experienced MDT remounted read-only after MDS relocation to other
cluster node.
They also started relocation of OSS services during the same time.
When they noticed they tried to stop the MDS. The attempt to stop MDS was
unsuccessful, the server got unresponsive and the other cluster node  fenced the
MDS server.
Then they run fsck which ended with huge number of errors, the repair was
unsuccessful. It ended with recreation of whole Lustre FS and restore from
backup.
Is it possible to determine the root cause from logs?
