I can't access the pastebin, did you verify if you hit the same issue
as Stefan referenced
(https://lists.ceph.io/hyperkitty/list/ceph-users@xxxxxxx/thread/KQ5A5OWRIUEOJBC7VILBGDIKPQGJQIWN/)? Before deleting or rebuilding anything I would first check what the root cause is. As Stefan said, don't mess with
MDS.
Zitat von "von Hoesslin, Volker" <Volker.Hoesslin@xxxxxxx>:
is there any chance to fix this? there are some "advanced metadata
repair tools"
(https://docs.ceph.com/en/latest/cephfs/disaster-recovery-experts/)
but i'm not realy sure is it the right way to handle this issue?
i have created an "backup" bevor any tries with this command:
cephfs-journal-tool journal export backup.bin
maybe can i delete the mds database and recreate it? is this possible?
volker.

i can not see what i have done wrong, this are my update steps:
Have you set allow_standby_replay to false?
Have you checked there were no more standby-replay daemons (ceph fs dump)?
