For the recent 12.2.3 Luminous release we've found that it is not possible to mount a device when using filestore [0] We are trying to find out how this was able to get pass our functional testing, in the meantime the workaround for this problem is to add the mount options in ceph.conf (as explained in the tracker ticket). Hopefully we can get another release soon enough to get this properly fixed for everyone. Apologies for anyone affected.
