[Gluster-users] Mount Fails when 1 of 2 Replicas is Down (GlusterFS 3.7.2)

[Gabriel Kuri]

I am able to reproduce a problem, which I think may be a bug, where if 1 of
the 2 replica servers for a volume is down, clients are unable to mount the
volume. I notice that if the replica that is down is on the same subnet as
the client, the client fails to mount the volume, but if the replica that
is down is on a different subnet, the client fails over properly and mounts
the volume.

Here are the errors from the server that is still up when the client is
unable to mount the volume when the replica on the same subnet as the
client is down. Ideas? Should I open a bug?
