[ovirt-users] Re: Device /dev/sdb excluded by a filter.\n

After looking at this, I hit upon something. Each machine in this cluster has two drives -- a 500gb and a 1 tb one. Each machine I was installing to the 500gb drive (going to put in bigger drives, but this was what was laying around) I went through and looked at the machines, and the one that was failing had the 500gb drive as the second drive. Reversed them, wiped everything and reloaded. Seems to be installing now.
