Description

Just tested 12.2.1 and was playing with multiple filesystems (CephFS), creating some and deleting some. After I have removed one FS, the list of FS available in the UI isn't updated and if you click on the one that was removed you get to an error page. Not a major issue as by default multiple FS is still disabled by default but just in case.

Restarting the Manager daemon and refreshing the dashboard page fixes the FS list

500 Internal Server Error

The server encountered an unexpected condition which prevented it from fulfilling the request.

Already reported an issue with cephmetrics who instructed me to create a tracker with ceph-mgr.

Hmm, the list in the menu is supposed to be updated every 5 seconds.

If you leave the console (the right click->inspect one, I don't know the proper name) open while you are removing the filesystem, can you see any javascript errors? If there is a javascript exception then the live updating can silently stop working.

Never mind, this was easy to reproduce locally. When a filesystem is deleted, ceph-mgr is somehow still holding on to an older FSMap, so this is nothing to do with the dashboard, it's some lower level issue.
