Hi, you can still get at LVs the same way as normal partitions. Maybe
some kernel modules need to be loaded though. Yesterday I successfully
used the latest Knoppix CD to access and recover my entire LV system.
With knoppix you simply need to type "modprobe dm-mod" and "vgscan" and
"vgscan -a y" and it'll get all the LVM stuff working.
