I can give a try again, but before migrated all db back to data I did compaction on all osd.

If in doubt, don't click any link nor open any attachment ! ________________________________ Please manually compact the DB using ceph-kvstore-tool for all the affected OSDs (or preferable every OSD in the cluster). Highly likely you're facing RocksDB performance degradation caused by prior bulk data removal. Setting bluefs_buffered_io to true (if not yet set) might be helpful as well.

At the time when slow ops started, in the osd log I can see: "7f2a8d68f700 1 heartbeat_map is_healthy 'OSD::osd_op_tp thread 0x7f2a70de5700' had timed out after 15" And this blocks the io until the radosgateway didn't restart itself. Is this a bug or something else? In the ceph.log I can see also that specific osd is reported failed from another osds: 2021-10-29T05:49:34.386857+0700 mon.server-3s01 (mon.0) 3576376 : cluster [DBG] osd.7 reported failed by osd.31 2021-10-29T05:49:34.454037+0700 mon.server-3s01 (mon.0) 3576377 : cluster [DBG] osd.7 reported failed by osd.22 2021-10-29T05:49:34.666758+0700 mon.server-3s01 (mon.0) 3576379 : cluster [DBG] osd.7 reported failed by osd.6 2021-10-29T05:49:34.807714+0700 mon.server-3s01 (mon.0) 3576382 : cluster [DBG] osd.7 reported failed by osd.11 Here is the osd log: https://justpaste.it/4x4h2 Here is the ceph.log itself: https://justpaste.it/5bk8k Here is some additional information regarding memory usage and backtrace...: https://justpaste.it/1tmjg Thank you _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx -- Igor Fedotov Ceph Lead Developer Looking for help with your Ceph cluster?
