Yep.

I tried this and when I tried listing the file, I got the same
consistency error message:

[defiant /etc/lvmconf]# vgcfgrestore -f /etc/lvmconf/vg00.conf.2.old -l
-n vg00
vgcfgrestore -- ERROR "vg_cfgrestore(): pv_check_consistency" restoring
volume group "vg00"

vg00.conf.2.old should be the one immediately prior to the "incident".

When I tried an actual restore, it groused about changing an active
volume group, so I guess I'll go single-user and try it again.

Not knowing what Norton has cabbaged, I would be happy if I could just
move the active extents from the damaged volume to another one long
enough to remobe, rebuild and reactivate it.

I'm using the one prior to the drive getting nortoned. :)
