[Gluster-users] Only one server in GlusterFS pair is working.

[Ernie Dunbar]

I've created a GlusterFS server pair, with GlusterFS v 3.2.5 (because
Debian uses that version, and all our servers are Debian), using the
official
guide:http://www.gluster.org/community/documentation/index.php/Getting_started_overview
[1] 

I'm able to successfully mount the Gluster volume from another machine
on the network and read and write files to it, but I can only connect to
server 1 and I only see files written to server 1. I show no files being
saved to server 2, and I can't mount the volume on server 2. I'm still
able to do a peer probe from server 2, and the status of the server
appears to be fine, so I don't understand what's going on here. 

Here's some output from the diagnostics I know about, any help in
diagnosing this problem would be much appreciated.
