It seems you didn't specify the kind of storage you are using...
Anything provided by the host itself or what?
All storage is NFS storage exported by the host itself. i didn't mention
it because it shouldn't have mattered -- the HE export mounted but the
others didn't.. Although it appears this may all have been due to the
network issues between engine and host -- once I added a workaround to
that issue the mounting issues seemed to resolve themselves.
I'm not sure why I'm having this network issue. The engine VM gets an ARP
Redirect and then can't reach the host anymore -- but of course the host
can reach the VM. It's a strange issue that I haven't been able to track
down (but is most likely not related to ovirt).
