Re: Cluster healthy, but 16.2.7 osd daemon upgrade says its unsafe to stop them?

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

 



Running

`ceph osd ok-to-stop 0`

shows:

{"ok_to_stop":false,"osds":[1],
"num_ok_pgs":25,"num_not_ok_pgs":2,
"bad_become_inactive":["13.a","13.11"],
"ok_become_degraded":["0.4","0.b","0.11","0.1a","0.1e","0.3c","2.5","2.10","3.19","3.1a","4.7","4.19","4.1e","6.10","12.1","12.6","15.9","21.17","21.18","36.8","36.13","41.7","41.1b","42.6","42.1a"]}
Error EBUSY: unsafe to stop osd(s) at this time (2 PGs are or would become offline)

What are “bad_become_inactive” PGs?
What can be done to make OSD into “ok-to-stop” (or override it)?

`ceph -s` still reports HEALT_OK and all PGs active+clean.

Upgrade to 16.2.8 still complains about non-stoppable OSDs and won't proceed.
