Ceph » CephFS

I used the mgr volumes module on my rook cluster to create a new cephfs. The orchestrator started up 2 MDS':

# ceph fs status

MDS version: ceph version 14.0.1-1580-gb88de88 (b88de8805910eca51830c609a9a1269a3d2be953) nautilus (dev)

After that, I noticed the standby-replay MDS was spewing a log message like this every second:

2018-12-17 14:39:29.762 7f0b2998a700  1 mds.0.0 replay_done (as standby)
2018-12-17 14:39:30.764 7f0b2998a700  1 mds.0.0 replay_done (as standby)
2018-12-17 14:39:31.765 7f0b2998a700  1 mds.0.0 replay_done (as standby)

Assuming this function running every second is expected behavior, we should probably tone down this log message.
