Use ceph fs set <fs_name> down true after this all mdses of fs fs_name will become standbys. Now you can cleanly remove everything. Wait for the fs to be shown as down in ceph status, the command above is non-blocking but the shutdown takes a long time. Try to disconnect all clients first.

It seems that the command to use is ceph fs rm fs1 --yes-i-really-mean-it and then delete the data and metadata pools with ceph osd pool delete but in many threads I noticed that you must shutdown the mds before running ceph fs rm. Is it still the case ? What happens in my configuration (I have 2 fs) ? If I stop mds1, the mds3 will take the management. If I stop mds3 what will mds2 do (try to manage the 2 fs or continue only with fs2) ? Thanks for your advices.
