I found a files_vg.conf and put it in /etc/lvmconf, did pvcreate and 
successful vgcfgrestores on all of them. I had to move the disks around 
a bit to make them appear in their old places since they're now in a new 
machine (vgcfgrestore complained otherwise). The bad disk is now at 
/dev/ide/host2/bus1/target1/lun0/disc

What did I do wrong (this time)?
