what do you mean with initialized?
mke2fs? in this case you will find lovely ext2 superblock copies in the
middle of your data, but then you could salvage most of your data.

lost partition table? just recreate it, it is not destructive?

lost lvm metadata?
i s'pose you don't have a metadata backup handy,
how were your lv's laid out in your vg?

i never tried this on linux, but on hp-ux pvcreate, vgcreate and lvcreate weren't
destructive, it only touched disk metadata. so you could try pvcreate,
vgcreate and lvcreate.
DO A BACKUP OF YOUR RAW DISK DATA FIRST
