Hi,
This is my first post to the list. I am happy to say that we have been
using Ovirt for 6 months with a few bumps, but it's mostly been ok.
Until tonight that is...
I had to do a maintenance that required rebooting both of our Hypervisor
nodes. Both of them run Fedora Core 18 and have been happy for months.
After rebooting them tonight, they will not attach to the storage. If
it matters, the storage is a server running LIO with a Fibre Channel target.

The strange thing is that I can see all of the LVM volumes for the VMs.
Both servers see the storage just fine. This error has me baffled and
it's a total show stopper since the cluster will not come back up.
If anyone can help, that would be very appreciated.
Thanks,
Dan
