Hi all!
I got this nice idea today to do a apt-get update/upgrade on my system.
when it was done I moved the box, and upon reboot my lvm was gone. I
think I had lvm1 before, but now it seems like I have
LVM version: 2.00.29 (2004-11-27)
Is this maybe what is causing the problem?
My lvm is at /dev/volume_group/mylv, my lvm consisted of hde,g,i
I noticed from dmesg that
LVM version 1.0.5+(22/07/2002) module loaded
and that devfs wouldn't be started... (no volumes or equiv)
Please advice, I got pretty much schoolwork on it...
Daniel
