Hi,

Environment:

Gluster Version: 3.8.3

Operating System: CentOS Linux 7 (Core)

Kernel: Linux 3.10.0-327.28.3.el7.x86_64

Architecture: x86-64

Replicated 3-Node Volume

~400GB of around a million files

Description of Problem:

One of the brick dies.  The only suspect log I see is in the etc-glusterfs-glusterd.vol.log (shown below).  Trying to get an idea of why the brick died and how it could be prevented in the future.

During this time, I was forcing replication (find . | xargs stat on the mount).  There were some services starting up as well that was using the gluster mount.

I haven't checked the code yet, but at a guess a brick op (in transit) failed here when the brick went down.

The message "I [MSGID: 106005] [glusterd-handler.c:5050:__glusterd_brick_rpc_notify] 0-management: Brick 172.17.32.28:/usr/local/volname/local-data/mirrored-data has disconnected from glusterd." repeated 34 times between [2016-09-13 20:01:50.033830] and [2016-09-13 20:03:40.010862]
