Hi all, sveikas, Thanks everyone for the tips and trying to help out! I've eventually raised a bug tracker for the case to get more developers involved: https://tracker.ceph.com/issues/69078 We tried decreasing osd_scrub_chunk_max from 25 to 15 as per Frédéric suggestion, but unfortunately did not observe any signs relief. One Squid user in reddit community thread confirmed the same after decreasing - no results. There are more users there in the thread that tried out various cluster configuration tunings, including osd_mclock_profile with high_recovery_ops but still no one managed to get any good results. Our scrub cycle runs 24/7 with no time windows/schedules therefore no possibilities of queue buildups due to time constrains. And yes - our longest running pg now is 23 days in the deep scrub (and still counting).
