[Gluster-users] Gluster volume not automounted when peer is down

Hi all,
We're trying to use gluster as a replicated volume. It works OK when both peers are up but when one peer is down and the other reboots, the "surviving" peer does not automount glusterfs. Furthermore, after the boot sequence is complete, it can be mounted without issue. It automounts fine when the peer is up during startup. I tried to google this and while I found some similar issues, I haven't found any solutions to my problem. Any insight would be appreciated. Thanks.
gluster volume info output (after startup):
Volume Name: rel-vol
Type: Replicate
Volume ID: 90cbe313-e9f9-42d9-a947-802315ab72b0
Status: Started
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: 10.250.1.1:/export/brick1
Brick2: 10.250.1.2:/export/brick1
gluster peer status output (after startup):
Number of Peers: 1
Hostname: 10.250.1.2
Uuid: 8d49b929-4660-4b1e-821b-bfcd6291f516
State: Peer in Cluster (Disconnected)
Original volume create command:
gluster volume create rel-vol rep 2 transport tcp 10.250.1.1:/export/brick1 10.250.1.2:/export/brick1
I am running Gluster 3.4.5 on OpenSuSE 12.2.

This is shorter than it is when it works, but maybe that's because the mount spawns some more processes.
Some ports are down:
