[Gluster-users] RPC program not available (req 1298437 330)

[Danny Lee]

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.
