They're all bluefs_single_shared_device, if I understand your
question. There's no room left on the devices to expand.
We started at quincy with this cluster, and didn't vary too much
from the Redhat Ceph storage 6 documentation for setting it up.

Hi John,
you haven't described your OSD volume configuration but you
might want
to try adding standalone DB volume if OSD uses LVM and has
single main
device only.
'ceph-volume lvm new-db' command is the preferred way of
doing that, see
https://docs.ceph.com/en/quincy/ceph-volume/lvm/newdb/
Thanks,
Igor
