Add multi MDS per node feature #1856

Closed jan--f closed 4 years ago

jan--f commented 4 years ago

Description: This pr enables deploying multiple MDS daemons per node. This is configured by adding mds_daemons_per_node: $n to the pillar. This can be done either globally (via /srv/pillar/ceph/stack/global.yml) or only on specific MDS nodes (via one of the files in /srv/pillar/ceph/stack/ceph/minions/). Rescind, restart and the shirnk to update functionality can handle multiple daemons per node.
