Hi Kamil, We got a similar setup, and thats our config: osd advanced osd_max_scrubs 1 osd advanced osd_recovery_max_active 4 osd advanced osd_recovery_max_single_start 1 osd advanced osd_recovery_sleep 0.000000 osd advanced osd_scrub_auto_repair true osd advanced osd_scrub_begin_hour 18 osd advanced osd_scrub_end_hour 6 osd advanced osd_scrub_invalid_stats true Our scrub start at 18:00 PM and finish at 6:00 PM, is enough and the first hours of each day system is ready and dont get any performance panic due scrubs. Implemented since 1 yr and no issue with scrubs. We use ceph config set for mantain this setting in quorum. Currently of cluster is S3 for main use.
