Re: [linux-lvm] Re: recovering the root partition under lvm



Hi,

I made some progress but still cannot boot. With the gentoo disk
I ran:

vgscan
vgchange -ay

and the system re-activated the volumes /dev/VolGroup00/LogVol00
and /dev/VolGroup00/LogVol00. In fact I can now mount (within
gentoo) this volume in e.g. /tmp/foo and see the whole tree.
However if I try to boot still doesn't do it coming out with the
same kernel panic message. So I guess there is something else I
have to do to "register" this volume at boot time. If so, can
someone tell me what it is? Many thanks in advance.

Dan
