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

[Kevin Hung]

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.

Console output below:

           During customization use CTRL-D to abort.
           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? (Yes, No)[No]: yes
