Re: [linux-lvm] LVM1 problem, exported volumegroup with one dead drive (fwd)



Hi Stefan,

I am working through the exact same scenario so you may like to look through my
posts and peoples advice in the LVM archive (july): 

http://lists.sistina.com/pipermail/linux-lvm/2003-July/subject.html

Basically I had 2 disks fail which were part of my VG. I now have 2 of 4 LV's
left and am trying to retrieve the data. As suggested the only way to recover
data from a partial VG is to upgrade to LVM2. 

I have done that and LVM2 can now activate my partial VG - but I haven't quite
retrieved the data from it yet.

Hope that helps,

Melinda
