Hello,
--
We have a two-node gluster cluster, running version 3.7.1, that hosts an oVirt storage domain. This afternoon I tried creating a template in oVirt, but within a minute VM's stopped responding and Gluster started generating errors like the following:
[2015-07-13 14:09:51.772629] W [rpcsvc.c:270:rpcsvc_program_actor] 0-rpc-service: RPC program not available (req 1298437 330) for 10.100.3.40:1021

I managed to get things in working order again by restarting glusterd and glusterfsd, but now one brick is down:
$sudo gluster volume status vmimage

Additionally in the etc-glusterfs-glusterd.vol.log I see these messages repeating every 3 seconds:

Can I get this brick back up without bringing the volume/cluster down?
