[GRLUG] LVM Data Recovery

[Jerry Groendyke]

I had a failed LVM recently and found the same article at Linux Journal.  I
was only to able find and recover one of my Volume Groups.  I built a new
server and added the replaced drive and original drive.  Then I went through
each step but ended up skipping lists 3-6.

Good luck,
Jeremy

I'm assuming you ran "vgchange -a y" and got an error?  
Does "pvdisplay --verbose" still show md0?
