<p>Hi all,</p>
<p>We recently had an issue with our ceph cluster which ended up
going into "Error" status after some drive failures. The system
stopped allowing writes for a while whilst it recovered. The ceph
cluster is healthy again but we seem to have a few instances that
have corrupt filesystems on them. They are all CentOS 7 instances.
We have got them into rescue mode to try and repair the FS with
"xfs_repair -L" However when we do that we get this:</p>

any debian based instances we could recover. It just seems to be
CentOS and having XFS on CentOS and ceph the instances don't
seem happy. This seems more low level to me in ceph rather than
a corrupt FS on a guest.</span></p>
