what is the output of vgs, lvs, pvs from the console?
Seems like either your lvm layer is bad, or the actual raid array is bad.
Have you tried to unmount this and then runs fsck?
Really weird that the local sr wasn't auto created for after install. It is like the first thing that happens when you connect to XS with XC.
Since it is not working you could just reinstall and try again, there shouldn't be an thing on it at this point.
