Thank you, Jason.
The report can be found at https://tracker.ceph.com/issues/47390
By the way, I think your link to the rbd issues should be the other
way around, http://tracker.ceph.com/issues/rbd gives me a 404. ;-)
This is better: https://tracker.ceph.com/projects/rbd/issues
Indeed -- thanks!
Regards,
Eugen

Hi *,
I was just testing rbd-mirror on ceph version 15.2.4-864-g0f510cb110
(0f510cb1101879a5941dfa1fa824bf97db6c3d08) octopus (stable) and
noticed mgr errors on the primary site (also in version 15.2.2):

The mirroring itself seems to work fine, I haven't noticed issues with
the image on the secondary site. I also uploaded a screenshot of the
dashboard [1], the installation is on openSUSE Leap 15.2.
I couldn't find a tracker issue or a report in bugzilla.opensuse.org,
but before creating a ticket I wanted to ask if this is a known issue.
The rbd-mirror panel works fine on the secondary site, I assume
because there is actually an rbd-mirror daemon running. Or maybe I
just misunderstand the purpose, but if there is no mirror daemon on
site A there shouldn't be an error message, should it?
Can you create a new tracker ticket at [1]? It looks like librbd is
not returning a default "unknown" status for the local site if you
aren't running "rbd-mirror" daemons. The dashboard is a little behind
in supporting all the latest RBD mirroring changes, in this case the
ability to see the global mirroring status from any site (local or
remote).

Eugen
