It wasn't that easy, that's what I did in the end:
1) vgchange -a n
2) vgexport -a
3) vgimport -a
4) vgscan --mknodes
5) vgchange -a y
Maybe 4) and 5) alone would do the trick... I don't remember which
livecd I used then, except for the fact that I had to reboot
with "dolvm2" option; now I have a tested "first aid kit" with notes on
paper (all my notes were on those discs at the time) with well known
and proven liveCDs.
When I have to resize/redesign my partitions I simply find easier rsync
plus a reboot.
I rsync the live system while I use it, than reboot to a liveCD to rsync
the file changed meanwhile (to minimize downtime). So I shortly tossed
LVM and since I live happily without.
