Hello Cephers,
On a new cluster, I only have 2 RBD block images, and the Dashboard
doesn't manage to list them correctly.
I have this message :
Warning
Displaying previously cached data for pool veeam-repos.
Sometime it disappears, but as soon as I reload or return to the listing
page, it's there.
What I've seen, is a high CPU load due to ceph-mgr on the active
manager.
And also stack-traces like this :

Also that, since I changed some features back and forth on one image :

But that's perhaps just becaus I open an Edit window on the image and it
does not have the datas.
The Edit window is empty, and I can't edit things, especially, I wan't
to resize the image.
Finally, I find a similar bug already registered here, but that seems
resolved for the owner :
https://tracker.ceph.com/issues/45308
Mmmm, as I read carrefully, it'about cephfs not rbd in that
stacktrace...
Am I the only one ?
Is there a work around ?
I really need the dashboard to be usable, because I want to delegate a
maximum of operations to people that don't need to have the rights to
connect to machines to use CLI.
And also don't have the skills to do so.
Have a good day,
