I certainly would agree with all. I don't know why I set it up that way.
I had formatted it by error when I installed F11 which is a con
regarding using a local SATA as the backup device :-). Some of the
LiveCds do not recognize LVM. I am pretty sure that the Fedora does, but
not 100% certain about Ubuntu or Knoppix, but I think the best bet is to
reformat to a single physical partition with EXT4.
