Description

Upon clicking the filesystems tab in the dashboard and clicking the FS name, the page loads with no details displayed on any of the tabs (Details/Clients/Directories) or errors shown in the browser.

Checking the MGR log I found the following:

Does listing images from CLI work? e.g.: rbd list -p <pool>

Correct, all commands like ceph -s and rbd list -p <pool> work fine and respond very quickly.

The only thing I can think of is before I was running the cluster without cephx, I had to enable it as hit this bug: https://tracker.ceph.com/issues/45091

I went through each service config file and enabled cephx and then rebooted the cluster and set the global config to be cephx, maybe somewhere else I need to enable cephx for the commands that the dashboard is trying to send and retrieve data with?

Both of these are now resolved since 15.2.2 on my cluster anyway.

I just upgraded our Nautilus cluster to Pacific (and switched to cephadm) this week and I'm seeing the same error message when I'm trying to list rbd images. The cephfs tab works fine. Listing rbd images via cli works fine as well. Please let me know if I can provide more information. The stack trace seems to be the same as previously reported so I won't paste it again unless you need me to.

Nevermind, the issue seemed to resolve itself. After a while the page actually shows our rbd images, seems like it takes a while to build the cache.
