Hi, I don't have an idea yet why that happens, but could you increase the debug level to see why it stops? What is the current ceph status? Thanks, Eugen Zitat von Denis Polom <denispolom@gmail.com>:

Hi

running Ceph Pacific 16.2.13.

we had full CephFS filesystem and after adding new HW we tried to start it but our MDS daemons are pushed to be standby and are removed from MDS map.

Filesystem was broken, so we repaired it with:

# ceph fs fail cephfs

# cephfs-journal-tool --rank=cephfs:0 event recover_dentries summary

# cephfs-journal-tool --rank=cephfs:0 journal reset

then I started ceph-mds service

and marked rank as repaired

mds after some time has switched to standby. Log is bellow.

I would appreciate any help to resolve this situation. Thank you.
