Hi Sage,
To give more context on this problem,
This cluster has two pools rbd and user-created.
Osd.12 is a primary for some other PG’s , but the problem happens for these
three PG’s.
$ sudo ceph osd lspools

And we couldn’t observe and peering events happening on the primary osd.
$ sudo ceph pg 0.49 query
Error ENOENT: i don't have pgid 0.49
$ sudo ceph pg 0.4d query
Error ENOENT: i don't have pgid 0.4d
$ sudo ceph pg 0.1c query
Error ENOENT: i don't have pgid 0.1c
Not able to explain why the peering was stuck. BTW, Rbd pool doesn’t contain
any data.

Stale means that the primary OSD for the PG went down and the status is stale.
They all seem to be from OSD.12... Seems like something is preventing that OSD
from reporting to the mon?
