I wouldn't adjust it. Do you have the impression that the mds is replaying the exact same ops every time the mds is restarting? or is it progressing and trimming the journal over time?
The only other advice I have is that 12.2.10 is quite old, and might miss some important replay/mem fixes. I'm thinking of one particular memory bloat issue we suffered (it manifested on a multi-mds cluster, so I am not sure if it is the root cause here https://tracker.ceph.com/issues/45090 ) I don't know enough about the changelog diffs to suggest upgrading right now in the middle of this outage. -- dan On Thu, Oct 22, 2020 at 4:14 PM David C <dcsysengin...@gmail.com> wrote: > > I've not touched the journal segments, current value of > mds_log_max_segments is 128.
