Description
From Ceph-users, https://www.spinics.net/lists/ceph-users/msg52869.html
After upgrading from 14.2.0 to 14.2.1, I've noticed PGs are frequently resetting their scrub and deep scrub time stamps to 0.000000. It's extra strange because the peers show timestamps for deep scrubs.
- First entry from a pg list at 7pm
$ grep 11.2f2 ~/pgs-active.7pm
11.2f2 691 0 0 0 2897477632 0 0 2091 active+clean 3h 7378'12291 8048:36261 [1,6,37]p1 [1,6,37]p1 2019-05-14 21:01:29.172460 2019-05-14 21:01:29.172460
- Next Entry 3 minutes later
$ ceph pg ls active |grep 11.2f2
11.2f2 695 0 0 0 2914713600 0 0 2091 active+clean 6s 7378'12291 8049:36330 [1,6,37]p1 [1,6,37]p1 0.000000 0.000000
Not sure if it's related, but this only happens to PG's who's primary OSD is one where osd_numa_node has been set.

The similarity to #40066 is so striking I just had to mention it and create a "Relates to" link.

Updated by David Zafman almost 5 years ago
- Assignee set to David Zafman
When auto repair is enabled a bug causes a regular scrub to reset time stamps which is only intended to happen when there were errors. This internally forces a deep-scrub in order to eventually auto repair.
