[ovirt-users] Unable to set up oVirt 4.0 HE using glusterfs storage

Hello, I thought I would ask the list if anyone is aware of this issue (or if I am doing something obviously wrong) before I submit a bug report. It looks like I am not able to choose glusterfs as a storage option for deploying a Hosted Engine in oVirt 4.0 Node Next. I believe it is failing to execute the following command: /sbin/gluster --mode=script --xml volume info mgmttank --remote-host=storage1.nullaxiom.com When I run the command manually, I get a blank line as output and checking in /var/log/glusterfs/cli.log, it seems to be exiting with error code -2. I have tried disabling the firewall on both host and gluster server, but it did not make a difference. I am able to manually mount the gluster volume on the host, and I had a working oVirt 3.6 installation using the same exact gluster server.

Continuing will configure this host for serving as hypervisor and create a VM where you have to install the engine afterwards. Are you sure you want to continue? (Yes, No)[Yes]: It has been detected that this program is executed through an SSH connection without using screen. Continuing with the installation may lead to broken installation if the network connection fails. It is highly recommended to abort the installation and run it inside a screen session using command "screen". Do you want to continue anyway?
