Description
I have 3 hosts, with lots of cores. I have a filesystem with ~150M files that requires several active MDS daemons to perform well. While one per host is a good default, I should be able to override that, eg:
ceph orch apply mds cephfs_1 3 --placement "6 dc-3558-421 mc-3015-421 m3-3101-421"
ceph orch daemon add mds cephfs_1 $(hostname -s)
^This command does deploy a second MDS on the host, in the right filesystem's namespace.
But I am concerned that it will be suddenly de-scheduled when applying other changes declaratively.
(I am testing on Octopus)
