Hi Felix,

I did start one or two of the VMs on the second node initially. That's
how I discovered that things had gone wrong. They did start but
gave horrendous errors and hung for half a minute at a time.

But for sure, there aren't any running now on the broken node. The
first node is running all of the VMs, quite smoothly fortunately.

So it's safe to assume that that was the point that the nodes started
to diverge, I believe. Certainly the second node has had the wrong IP
address on the NIC facing the storage since before I attempted to
start any of the VMs.

Not sure I even can copy the second node's data - it's not
communicating with the storage at all. But I only need the first node's

Thanks again,
