IIUC the OSDs that expose "had timed out after 15" are failing to start
up. Is that correct or I missed something? I meant trying compaction
for them...

Hi Igor,
thanks for your response.
And what's the target Octopus release?
ceph version 15.2.17 (8a82819d84cf884bd39c17e3236e0632ac146dc4) octopus (stable)
I'm afraid I don't have the luxury right now to take OSDs down or add extra load with an on-line compaction. I would really appreciate a way to make the OSDs more crash tolerant until I have full redundancy again. Is there a setting that increases the OPS timeout or is there a way to restrict the load to tolerable levels?
Best regards,

Hi Frank,
you might want to compact RocksDB by ceph-kvstore-tool for those OSDs
which are showing
"heartbeat_map is_healthy 'OSD::osd_op_tp thread 0x7f1886536700' had timed out after 15"
I could see such an error after bulk data removal and following severe
DB performance drop pretty often.
Thanks,
Igor
