Hi! Yes, it looks like you hit the same bug. My corruption back then happed because the server was out-of-memory and OSDs restarted and crashed quickly again and again for quite some time... What I think happens is that the journals somehow get out of sync between OSDs, which is something that should definitely not happen under the intended consistency guarantees. However, I've managed to resolve it back then by deleting the PG with the older log (under the assumption that the newer one is the more recent and better one). This only works if enough shards of that PG are available of course, and then the regular recovery process will restore the missing shards again. I hope my script still works for you. If you need any help, I'll see what I can do :) If things fail, you can still manually import the exported-and-deleted PGs back into any OSD (which will probably cause the other OSDs of the PG to crash since then the logs won't overlap once again).

Wait for recovery to finish so you know whether any data from the down OSDs is required. If not just reprovision them.
Recovery will not finish from this state as several PGs are down and/or stale.
Thanks for your input so far.
It looks like this issue: https://tracker.ceph.com/issues/36337 We will try to use the linked Python script to repair the OSD. ceph-bluestore-tool repair did not find anything.
