[ovirt-users] glusterFS is not independent?

Hello, I'm very new to oVirt and glusterFS, so maybe I got something wrong... I have the oVirt engine installed on a separate server and I have also two physical nodes. On every node I configure glusterFS, the volume is in distribution mode and have only one brick, from is one node. Both volumes I also add to its own storage domain. The idea was, that both storage domains are independent from each other, that I can turn of one node and only turn it on, when I need it. But now I have the problem, that when I turn of on node, both storage domains goes down. and the volume shows the the brick is not available. Is there a way to fix this? Regards Jonathan
