Are there any other settings that should be added here?

By 'settings' you mean any other config options, don't you?

I had a look at the config options page and found 32 OSD options where 'scrub' is mentioned:

• osd_debug_deep_scrub_sleep -> Inject an expensive sleep during deep scrub IO to make it easier to induce preemption
• osd_deep_scrub_interval -> Deep scrub each PG (i.e., verify data checksums) at least this often
• osd_deep_scrub_keys -> Number of keys to read from an object at a time during deep scrub
• osd_deep_scrub_large_omap_object_key_threshold -> Warn when we encounter an object with more omap keys than this
• osd_deep_scrub_large_omap_object_value_sum_threshold -> Warn when we encounter an object with more omap key bytes than this
• osd_deep_scrub_randomize_ratio -> Scrubs will randomly become deep scrubs at this rate (0.15 -> 15% of scrubs are deep)
• osd_deep_scrub_stride -> Number of bytes to read from an object at a time during deep scrub
• osd_deep_scrub_update_digest_min_age -> Update overall object digest only if object was last modified longer ago than this
• osd_max_scrubs -> Maximum concurrent scrubs on a single OSD
• osd_op_queue_mclock_scrub_lim -> mclock weight of limit requests
• osd_op_queue_mclock_scrub_res -> mclock reservation of scrub requests
• osd_op_queue_mclock_scrub_wgt -> mclock weight of scrub requests
• osd_requested_scrub_priority
• osd_scrub_auto_repair -> Automatically repair damaged objects detected during scrub
• osd_scrub_auto_repair_num_errors -> Maximum number of detected errors to automatically repair
• osd_scrub_backoff_ratio -> Backoff ratio for scheduling scrubs
• osd_scrub_begin_hour -> Restrict scrubbing to this hour of the day or later
• osd_scrub_begin_week_day -> Restrict scrubbing to this day of the week or later
• osd_scrub_chunk_max -> Maximum number of objects to scrub in a single chunk
• osd_scrub_chunk_min -> Minimum number of objects to scrub in a single chunk
• osd_scrub_cost -> Cost for scrub operations in work queue
• osd_scrub_during_recovery -> Allow scrubbing when PGs on the OSD are undergoing recovery
• osd_scrub_end_hour -> Restrict scrubbing to hours of the day earlier than this
• osd_scrub_end_week_day -> Restrict scrubbing to days of the week earlier than this
• osd_scrub_interval_randomize_ratio -> Ratio of scrub interval to randomly vary
• osd_scrub_invalid_stats
• osd_scrub_load_threshold -> Allow scrubbing when system load divided by number of CPUs is below this value
• osd_scrub_max_interval -> Scrub each PG no less often than this interval
• osd_scrub_max_preemptions -> Set the maximum number of times we will preempt a deep scrub due to a client operation before blockinient IO to complete the scrub
• osd_scrub_min_interval -> Scrub each PG no more often than this interval
• osd_scrub_priority -> Priority for scrub operations in work queue
• osd_scrub_sleep -> Duration to inject a delay during scrubbing
