Hi Erich,
im not sure about this specific
error message, but "ceph fs status" sometimes did fail me end of last year/in the
beginning of the year.
Restarting ALL mon, mgr AND mds fixed it at the time.
Best regards,
Gunnar

Hi Eugen,
Thanks for the tip! I just ran:
ceph orch daemon restart mgr.pr-md-01.jemmdf
(my specific mgr instance)
And it restarted my primary mgr daemon, and in the process failed over
to my standby mgr daemon on another server. That went smoothly.
Unfortunately, I still cannot get 'ceph fs status' to work (on any node)...
# ceph fs status
