Ben may be on to something. If you're using NetworkManager, there may be
a chicken and egg problem due to the lack of a hardware link being
established (no switch). What if you mount from localhost?

Hi Greg. I don't know if this is the thread I replied to before but it still
sound to me like your NICs aren't fully up when the gluster mount is getting
mounted. The _netdev(at least the version in RHEL 6, I haven't looked at
others) doesn't check if the NIC is fully up, it only looks to see if the NW
manager lock file exists. When I saw this happen in my tests the lockfile
existed but the NIC was still initializing and unable to send/receive traffic
to mount the FS. I was able to put a sleep in the initscript to work around
this:
# diff -pruN /etc/rc.d/init.d/netfs /tmp/initrd/netfs

I just used the sleep for testing, the preferred way of dealing with this is
probably using the LINKDELAY option in your
/etc/sysconfig/network-scripts/ifcfg-* script. This variable will cause the
network scripts to delay $LINKDELAY number of seconds. Can you try testing
with either of those options to see if you are able to mount at boot?

the replicated volume anymore
This time after rebooting both nodes, neither one shows /firewall-scripts
mounted after a login. But mount -av by hand is successful on both nodes.
Fw1 and fw2 both behave identically. Here is what fw1 looks like. Fw2 is
identical. This aspect of the problem is screaming timing glitch.
