[ovirt-users] host gaga and ovirt cannt control it.

Ok, I have struggled with this for 2 hours now, glusterp2 and the ovirt server are basically not talking at all. I have rebooted both, I dont know how many times. Reading via google there seems to be no fix for this bar a manual hack of the ovirt server's database to delete the host glusterp2? or it it re-install from scratch time? If I have to re-install from scratch, is it best to go back a version of ovirt say to 3.6?
