Its seems that your brick process are offline or all brick process have crashed. Could you paste output of #gluster volume status and #gluster volume info command and attach core file.
Very interesting. They were reporting both bricks offline, but the
processes on both servers were still running. Restarting glusterfsd on
one of the servers brought them both back online.
I am going to have to take a closer look at the logs on the servers.
Even after bringing them back up, the client is still reporting
"Transport endpoint is not connected". Is there anything other than a
reboot that will change this state on the client?
