Like Dave said. :(

/dev/sdc7 is your new home, not the old one you want to recover, right?

sda 1,2,5,6,7,8 are pv's
sdc 1,2 are pv's too
sdc 3,4,7,8 are (well, probably, they were) in fstab

Herman, two questions
Your old home was a normal partition or already a lvm volume?
Do you know in what partition/lv your old home is?
