it was 2G that was overwritten, not just 2M. so i'm quite willing to
believe that it's unrecoverable. but that "testdisk" utility claims to

reports.
as for disk partitioning, i was told that half the drive was
allocated to a "home" LV, but i have no idea where that would have
started or how badly it would have been corrupted.
In /etc/lvm/backup you should find a file describing that volume group.
It will show what partition each PV was on ("Hint only") and where the
extents for each LV were located. If you can figure out where the PV's
partition started and re-create that in the partition table, you can
then do a "vgcfgrestore" to rebuild the VG metadata. If your old home
LV was beyond the overwritten area, you should get it back.
If you don't find the VG in /etc/lvm/backup, try /etc/lvm/archive.
