[ovirt-users] oVIRT 4.0.6 / Pools / Spinning up Pool (Cannot get parent volume?)

[Devin Acosta]

I am trying to get a pool going within oVIRT. When I go to create the pool
it errors out on trying to spin up the instances. However if i manually
spin up an instance from the Template it comes up with no issues. I noticed
inside the vdsm.log i see messages about "'Cannot get parent volume' - code
216", however I looked at the NFS share and the permissions appear right
vdsm:kvm
