'state dump' is the dump of state the process at the time. It can give 
details like how many calls pending, how much memory used, where, etc etc.

You can get it by sending 'SIGUSR1' to proces. Issue below command.

bash# kill -USR1 <pid of glusterfsd brick process>

By 'subvolume' Avati meant, the brick process. Here, in your specific 
case, get the statedump of 'Brick3' from your 'gluster volume info' details.

If '$hostname:$exportdir' is your brick, you can determine which process 
is exporting that brick by below steps

bash# ssh -l root $hostname ps aux | grep $exportdir

Hope this is informative, also I hope you still have the all the process 
running (if you had done 'gluster volume stop' any time inbetween or 
restarted the node/brick process, you may want to re-create the issue 
and then take statedump.
