One of the more interesting things revealed by searching for "recover
linux LVM" was the suggestion to use lvimport:

--------------

Try booting from CD-ROM and use vgimport with the -f flag to get
your LVM back:


vgimport -f -v data /dev/hda1 /dev/hda5 /dev/hda7


When booting from disk next time, save the configuration with
vgcfgbackup.

In my case it'd be

vgimport -f -v VolGroup00 /dev/sda2 /dev/sdb1

Does anyone know if this is likely to work? What does this command
actually do when run off the rescue cd? Where is actually the
configuration stored when I shutdown from the rescue disk and boots off
the harddisks again? Will the fact that the root filesystem is on the
VolGroup00 cause any problems?
