[ovirt-users] ovirt-3.6 and glusterfs doc

Fri Jan 29 21:29:57 UTC 2016

[root at ovirt3 test vdsm]# gluster volume info 
--remote-host=ovirt3.test.j2noc.com
No volumes present

I thought ovirt was suppose to create the volume. Am I suppose to create 
it first?

Thank you for the doc, I'll read through that...
