Hey Dave,

Thanks for the reply. I've just tried adding lvm to my boot runlevel. 
Unfortunately, its exactly the same. The LVM service does now start, but 
I'm still told that no volumes can be found.

I've verified that the raid arrays are all running ok, however LVM just 
seems to have lost all my partitions...which seems crazy.

I really, really hope that the upgrade doesn't mean i've lost data.

Thanks
