Hello everyone. I have a cluster with 8321 pgs and recently I started to get pg not deep-scrub warnings. The reason is that I reduced max_scrub to avoid the impact of scrub on IO. Here is my current scrub configuration: ~]# ceph tell osd.1 config show|grep scrub "mds_max_scrub_ops_in_progress": "5", "mon_scrub_inject_crc_mismatch": "0.000000", "mon_scrub_inject_missing_keys": "0.000000", "mon_scrub_interval": "86400", "mon_scrub_max_keys": "100", "mon_scrub_timeout": "300", "mon_warn_pg_not_deep_scrubbed_ratio": "0.800000", "mon_warn_pg_not_scrubbed_ratio": "0.500000", "osd_debug_deep_scrub_sleep": "0.000000", "osd_deep_scrub_interval": "1296000.000000", "osd_deep_scrub_keys": "1024", "osd_deep_scrub_large_omap_object_key_threshold": "200000", "osd_deep_scrub_large_omap_object_value_sum_threshold": "1073741824", "osd_deep_scrub_randomize_ratio": "0.080000", "osd_deep_scrub_stride": "131072", "osd_deep_scrub_update_digest_min_age": "7200", "osd_max_scrubs": "1", "osd_requested_scrub_priority": "120", "osd_scrub_auto_repair": "false", "osd_scrub_auto_repair_num_errors": "5", "osd_scrub_backoff_ratio": "0.660000", "osd_scrub_begin_hour": "0", "osd_scrub_begin_week_day": "0", "osd_scrub_chunk_max": "25", "osd_scrub_chunk_min": "5", "osd_scrub_cost": "52428800", "osd_scrub_during_recovery": "false", "osd_scrub_end_hour": "0", "osd_scrub_end_week_day": "0", "osd_scrub_extended_sleep": "0.000000", "osd_scrub_interval_randomize_ratio": "0.500000", "osd_scrub_invalid_stats": "true", "osd_scrub_load_threshold": "0.500000", "osd_scrub_max_interval": "1296000.000000", "osd_scrub_max_preemptions": "5", "osd_scrub_min_interval": "259200.000000", "osd_scrub_priority": "5", "osd_scrub_sleep": "0.000000", I am currently trying to adjust the interval of scrub. Is there a calculation formula that can be used to easily configure the scrub/deepscrub strategy? At present, there is only the adjustment of individual values, and then it is a long wait, and there may be no progress in the end.
