Eco,
they all appear to be using 24007 and 24009, none of them are running on 24010 or 24011.

Your right Eco
I am only able to telnet on port 24007, ports 24009, 24010 and 24011 are all connection refused . Iptables is not running on any of the machines
mseas-data 24007, 24009 are open, 24010 and 24011 closed
nas-0-0 24007 open, 24009,24010 and 24011 closed
nas-0-1 24007 open, 24009,24010 and 24011 closed
Steve

Meaning, run a recursive find against the client mount point
(/mount/glusterfs is used as an example in the docs). This should solve
the specific issue of the files not being visible.
However, the issue of the disk space discrepancy is different. From the
df output, the only filesystem with 18GB is / on the mseas-data node, I
assume this is where you are mounting from?
If so, then the issue goes back to one of connectivity, the gluster
bricks most likely are still not being connected to, which may actually
be the root cause of both problems.
Can you confirm that iptables is off on all hosts (and from any client
you would connect from)? I had seen your previous tests with telnet,
was this done from and to all hosts from the client machine?
Make sure that at a minimum you can hit 24007, 24009, 24010 and 24011.
This will test the management port and the expected initial port for
each of the bricks in the volume.
Thanks,
Eco
