Hard to reconstruct in detail, but as soon as the raid device has
'enough' failed devices, it doesn't respond to any request. It simply
isn't readable anymore.

Don't think that's a bug in pvmove. Neigther in linux-softraid - just a
very bad accident. (If a bug at all, I would say it's an ATA bug...)

I could restore the single PV to a state, where it had no LEs on it.
(using vgcfgrestore from lvm 1). That way vgscan now finds just enough
LEs and I can activate the VG again.

Lucky me... ;-)

Thanks anyway.
