Description
I used the mgr volumes module on my rook cluster to create a new cephfs. The orchestrator started up 2 MDS':
# ceph fs status a - 2 clients = +------+----------------+-----+---------------+-------+-------+ | Rank | State | MDS | Activity | dns | inos | +------+----------------+-----+---------------+-------+-------+ | 0 | active | a-b | Reqs: 0 /s | 10 | 13 | | 0-s | standby-replay | a-a | Evts: 0 /s | 0 | 3 | +------+----------------+-----+---------------+-------+-------+ +---------------+----------+-------+-------+ | Pool | type | used | avail | +---------------+----------+-------+-------+ | cephfs.a.meta | metadata | 8594 | 70.9G | | cephfs.a.data | data | 0 | 70.9G | +---------------+----------+-------+-------+ +-------------+ | Standby MDS | +-------------+ +-------------+ 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.
