LVM1, I assume ?

Raplace the dead hard disk with one of the same size, pvcreate the new one
and vgcfgrestore the data to it. Run "vgscan ; vgchange -ay" afterwards
(which will probably run anyway in one of your boot scripts).

- Or -

Install device-mapper and LVM2 and use LVM2's partial activation feature
(vgchange -ay -P). You must recreate the VG after you saved any data still
accessible.

- Or -

if you want a quick hack taking the risk that accessing parts of
logical volumes mapped to the dead disk (assuming your volume grous
name is "VG" and that VG is the only one in the system):

# mkdir /etc/lvmtab.d
# cp /etc/lvmconf/VG.conf /etc/lvmtab.d/
# echo -ne "VG\0" > /etc/lvmtab
# vgchange -ay

That should get you temporary access to all data you still _can_ access.
Save it and if you don't replace the failed disk, recreate your volume
group, logical volumes and filesystems in order to restore your data.
