Hi, we have a small cluster running on jewel 10.2.7; NL-SAS disks only, osd data and journal co located on the disks; main purpose rgw secondary zone.
Since the upgrade to jewel, whenever a deep scrub starts on one of the rgw index pool pg's, slow requests start piling up and rgw requests are blocked after some hours. The deep-scrub doesn't seem to finish (still running after +11 hours) and only escape I found so far is a restart of the primary osd holding the pg. Maybe important to know, we have some large rgw buckets regarding #objects (+ 3 million) with only index sharding of 8. scrub related settings: osd scrub sleep = 0.1 osd scrub during recovery = False osd scrub priority = 1 osd deep scrub stride = 1048576 osd scrub chunk min = 1 osd scrub chunk max = 1 Any help on debugging / resolving would be very much appreciated... regards, Sam _______________________________________________ ceph-users mailing list [email protected] http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
