[Gluster-users] Fail of one brick lead to crash VMs

I faced a problem a week ago.
In our environment we have three servers in a quorum. The gluster volume
is spreaded over two bricks and has the type replicated.
We now, for simulating a fail of one brick, isolated one of the two
bricks with iptables, so that communication to the other two peers
wasn't possible anymore.
After that VMs (opennebula) which had I/O in this time crashed.
We stopped the glusterfsd hard (kill -9) and restarted it, what made
things work again (Certainly we also had to restart the failed VMs). But
I think this shouldn't happen. Since quorum was not reached (2/3 hosts
were still up and connected).
Here some infos of our system:
OS: CentOS Linux release 7.1.1503
Glusterfs version: glusterfs 3.7.3
gluster volume info:
Volume Name: cluster1
Number of Bricks: 1 x 2 = 2
Hope you can help us.
Thanks a lot.
