Re: How to recover data corrupted by vgcreate

[Jonathan E Brassow <jbrassow@redhat.com>]

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.
