I am merely putting the client to sleep and waking it up. When it is up,
running ls on the mounted directory. As far as I am concerned at very high
level I am doing the same thing. All are running 3.13 kernel Debian provided.
When that infinite loop of decrypt error happened, I waited about 10 minutes
before I restarted MDS.
Last time MDS crashed restarting MDS didn't get out of that degraded mode
without me restarting the OSD for hours. That's why I started restarting OSDs
shortly after MDS restarts. Next time I'll try to wait a bit more.

Hong

This sounds different than the scenario you initially described, with
a client going to sleep. Exactly what are you doing?

That sounds normal -- the MDS has to replay its journal when it
restarts. It shouldn't take too long, but restarting OSDs definitely
won't help since the MDS is trying to read data off of them.
