Hi Alex.  You are correct when you see the "Transport endpoint is not connected." it usually means that the client is unable to access the server.  Check gluster v status and make sure all your bricks are online.  Try to unmount / remount the client if you see everything is up.  If you still cant access and everythin is online I would do some basic NW troubleshooting, make sure selinux is off on the servers, and check /var/log/glusterfs/bricks for errors on each of the servers.  If you see any error messages of the severity { M | A | C | E } pastebin them to me and I'll have a look.
