Good morning!
It's a novelty for our situation. The list of cluster locks now contains entries for the addresses of the servers on which the mds is running. The lifetime of the records is a day. For now, we decided to wait until the records are deleted and see how the cluster behaves.
Best regards!

We have a version in containers.
Here is a fresh log from the first mds. Actually, this is the whole log, after it is restarted.

This doesn't reveal much. Can you share MDS logs?
We are trying to do cephfs-journal-tool --rank cephfs: 0 journal inspect and the utility does nothing.
If the ranks are unavailable, it won't do anything. Do you see any log statements like "Couldn't determine MDS rank."?
We thought that mds were blocking their journals, and turned them off. But the utility does not work, and ceph -s says that one mds is running, although we checked that we stopped all processes.
It turns out somewhere else there is a blocking of magazines.
What else can be done? Do you want to restart the monitors?

Тема: Re: Re: CephFS 16.2.10 problem
Hi,
The log you shared indicates that MDS is waiting for the latest OSDMap epoch. The epoch number in log line 123138 is the epoch of last failure. Any MDS entering replay state needs at least this osdmap epoch to ensure the blocklist propopates. If the epoch is less than this then it just goes back to waiting.
I have limited knowledge about the OSDs but you had mentioned in your initial mail about executing some OSD commands, I'm not sure if the issue lies there. You can check and share OSD logs or maybe `ceph -s` could reveal some potential warnings.

Good afternoon
We tried to leave only one mds, stopped others, even deleted one, and turned off the requirement for stand-by mds. Nothing helped, mds remained in the status of replays.
Current situation: we now have two active mds in the status of replays, and one in stand-by.
At the same time, in the logs we see a message
mds.0.660178 waiting for osdmap 123138 (which blocklists prior instance)
At the same time, there is no activity on both mds.
The launch of the cephfs-journal-tool journal inspect utility does not produce any results - the utility worked for 12 hours and did not produce anything, we stopped it.
Maybe the problem is this blocking? How to remove it?

I assume you tried to start just one mds and wait until it would come up as active (before starting the others)?
