I tried other ones, but every time, I'm getting:
vgcfgrestore -- VGDA for "BigAssLVMRaid" successfully restored to physical
volume "/dev/rd/disc0/part7"
vgcfgrestore -- you may not have an actual backup of restored volume group
"BigAssLVMRaid"

Am I supposed to give a special flag to vgcfgrestore, or maybe pvcreate?
(I did not use the default physicalextentsize)

As a reminder, I am currently running this command:
FILE=/etc/lvmconf/BigAssLVMRaid.conf.2.old; vgcfgrestore -f $FILE -n BigAssLVMRaid -ll; read a; pvcreate -yff `cat /tmp/partlist`; for pv in `cat /tmp/partlist `; do vgcfgrestore -f $FILE -n BigAssLVMRaid $pv; done; vgscan

Short of all this, can I re-create the VG the same way I did the first
time, and hope to get my filesytem again if I recreate the same LVs?
(like I can do with software raid)

This VG was working fine before I restored the other one (active and all)

Ok. I guess I'll know to steer clear  from snapshots in the meantime, but if
LVM doesn't even allow  me to recover a VG that  hasn't been overwriten with
random data, I don't know how much data I'm willing to trust to it...

Either way, thanks for your help.
