I am wondering if there is a way I can plug these two physical disks
into another Linux box and access the file system that's on the
logical volume group. I looked at the LVM FAQ about moving groups, but
it assumes you can run commands on the old system before moving to the
new system. In this case, the old system is gone.
That is not a problem, it just helps if you export them first, as then
they will not clash with any existing volume group, if you have
different volume group names, just plug them into the new machine. On
booting you might just get lucky and it will activate the volume group.
If you have the same names, your need to boot from a rescue disk, then
rename the volume group to something else (vgrename). Then they should
work fine with the alternative system. If you don't have root on LVM
your alternative systems "rescue" mode might be enough to bring things
online.
If you do boot from a rescue disk you can use
pvscan
vgscan
vgchange -a y
To bring up the disks if it does not do it automatically. You need to do
a vgchange -a n before you can rename a volume group.
You rescue disk may require you to type
lvm pvscan
lvm vgscan
etc. Some
