I'm learning as I go here, I had never heard of Linux LVM until
yesterday. This is a plain vanilla fedora installation. /dev/sdb2
contains the root and swap logical volumes. /dev/sdb1 is home. kpartx
-a /dev/sdb creates /dev/sdb1 and /dev/sdb2,
and kpartx -d /dev/sdb deletes both of them. Neither state made a bit
of difference as far as accessing 'home'.
Pvscan shows one pv: /dev/sdb2.
BTW, I forgot to mention that I'm booting from the latest Ubuntu rescure
remix CD (10.10). My Fedora CD won't boot - it loops during boot.
Someone suggested Knoppix, but that loops also.
