Also, pools don't work by default if only one replica is left. You better add a second OSD or just do a mkcephfs again with a second OSD in the configuration. Just a reminder, it's also in the docs, but CephFS is still in beta, so expect weird things to happen. It can however not hurt to play with it! P.S.: There's also a new and shiny ceph-users list since two days ago, might want to subscribe there.
