Oki, since I had a LVM with broken loop support, I'll try with a spare disk...

----- s n i p -----
[papadoc.root]# pvcreate /dev/sdh1
pvcreate -- physical volume "/dev/sdh1" successfully created

[papadoc.root]# vgcfgrestore -f /etc/lvmconf/vg1.conf -n vg1 /dev/sdh1
vgcfgrestore -- physical volume "/dev/sdh1" doesn't belong to volume group "vg1"

[papadoc.root]# vgcfgrestore -f /etc/lvmconf/vg1.conf -n vg1 -o /dev/sdg1 /dev/sdh1
vgcfgrestore -- size of physical volume /dev/sdh1 differs from backup
----- s n i p -----

I'm not sure exactly how big my previous (now crashed) sdg disk was, or how big
the sdg1 partition was...

How do I:

        1. Find out _exactly_ how big the sdg1 partition was (the only
           number I have is '15.5Gb')?
        or
        2. Use the  existing sdh1 even though the size don't match?

----- s n i p ----
[papadoc.root]# pvdisplay -v /dev/sdh1
pvdisplay -- getting physical volume size
pvdisplay -- "/dev/sdh1" is a new physical volume of 2.22 GB

Not nearly the same size as the original sdg1, but....
