[ovirt-users] Cannot run specific VM in one node

[Diego Remolina]

Hi Joop,

There is currently no split brain in my gluster file systems. The
virtualization setup is a two node hypervisor (ysmha01 and ysmha02),
but I have a 3 node gluster where one node has no bricks
(10.0.1.6->ysmha01, 10.0.1.7->ysmha02 and 10.0.1.5 no bricks), but
helps define quorum, see below:

[root at ysmha01 ~]# gluster volume status engine
Status of volume: engine
