[ovirt-users] can not use iscsi storage type on ovirtandGlusterfs hyper-converged environment

A wild guess, not sure if it is related - can you check if multipathd
service is enabled. If you set up your oVirt-Gluster hyperconverged
environment via gdeploy, multipathd service is disabled and the
/etc/multipath.conf is edited to blacklist all devices - this was to fix
https://bugzilla.redhat.com/show_bug.cgi?id=1303940

Since you mention you're unable to add iscsi storage only in this
environment, thought it's worth checking.
