I read recently on this list that LVM is not portable across CPU architectures, so that you can't just upgrade your mobo to AMD64 and retain your /home.
Well, now you've got me curious. If so, this is potentially a serious issue, because most rescue disks are 32-bit. If it's true, then an LVM created on a 64-bit system wouldn't be readable with a 32- bit rescue disk. It also might have implications for things like USB hard disks. (These are getting big enough where it might start to make sense to LVM them -- I have one USB array that's 1.5 TB.)
I happen to have a spare AMD64 system and a couple of spare IA32 systems, all with hot-swap drive bays that take the same sleds, so I may try this and see what happens.
