The "rbdmap" unit needs rbdmap and fstab to be configured for each volume, what
if the map and mount are done by applications instead of the system unit? See,
we don't write each volume info into /etc/ceph/rbdmap /etc/fstab, and if the
"rbdmap" systemd unit is stopped unexpected, not by rebootin

The hope is to be able to provide scale-out storage, that will be performant
enough to use as a primary fs-based data store for research data (right now we

Hello cephers,
as described - we also have the slow requests in our setup.
We recently updated from ceph 12.2.4 to 12.2.10, updated Ubuntu 16.04 to the
