[linux-lvm] How to recover data corrupted by vgcreate

[Jonathan E Brassow]

I'm not familiar exactly with how the metadata gets laid on disk, but I 
would think you could just 'vgcreate vg_name /dev/hdd2' (you did this 
already) then 'lvcreate -n <lvname> -l <max size> vg_name'...  This of 
course assumes that the previous lv resided wholly on /dev/hdd2.  Then 
try mounting the new lv and see what happens.
