pg deep scrubbing issue

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi Everyone,

My Nautilus cluster of 6 nodes, 180 OSDs, is having a weird issue I don’t know how to troubleshoot.

I started receiving  health warning issues, and the number of PGS not deep-scrubbed in time has been increasing.

# ceph health detail
HEALTH_WARN 3013 pgs not scrubbed in time
PG_NOT_SCRUBBED 3013 pgs not scrubbed in time
    pg 1.e99 not scrubbed since 2022-12-21 11:01:10.403525

    pg 1.e89 not scrubbed since 2022-12-18 07:20:13.328540
    ...
    2963 more pgs…

Strangely, ceph pg dump gives shows every other PG with 0 objects.  An attempt to perform a deep scrub (or scrub) on one of these PGs does nothing.   The cluster appears to be running fine, but obviously there’s an issue.   What should my next steps be to troubleshoot ?
