I created one ceph cluster.

node-1: mon, mgr, osd.0, mds 

node-2: mon, mgr, osd.1, mds

node-3: mon, mgr, osd.2, mds

When the cluster is working normally, using command "mount -t ceph <node-*-ip:6789>:/ /mnt -o name=admin,secret=<admin client secret>" to mount is ok.

But when a node unusual down(like poweroff), and using same command to mount, it will be hanging long time(maybe more then 1 minutes).

I trying to configure "mds reconnect timeout = 0" in ceph.conf,  mount time has been shortened. 

My Question:

What are the configurations that affect the ceph file system mount in this scenario? 

BRs.
