2019-03-21 16:32:10 -0600 commented question ceph-fs No MDS detected using current configuration

The Juju charms I'm using are provided by the Openstack Dev team, and I suspect this is related to the way the charm works, as it's designed to work with an Openstack deployment.
2019-03-21 05:53:10 -0600 asked a question ceph-fs No MDS detected using current configuration

I'm deploying Ceph via Juju. Using the lastest version of the openstack-charmers-next osd, mon and fs charms. Host OS is Bionic and install source is cloud:bionic-rocky. 3 OSDs (metal), 3 mons (lxd) and 2 MDS (lxd).

Everything stands up great, and initially the MDS works (and the cephfs_data and cephfs_metadata pools are created). However as the install is settling, once the second and third mons come online the MDS status changes to "No MDS detected using current configuration" and the fs pools go offline.

It looks like this:

Every 2.0s: juju status --color
