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.
Regards
Manuel

Asunto: [ceph-users] Handling scrubbing/deep scrubbing
Hi,
I've 4 node cluster with 13x15TB 7.2k OSDs each and around 300TB data inside.
I'm having issues with deep scrub/scrub not being done in time, any tips to
handle these operations with large disks like this?
osd pool default size = 2
osd deep scrub interval = 2592000
osd scrub begin hour = 23
osd scrub end hour = 5
osd scrub sleep = 0.1
Cheers,
Kamil
