However, I still have some questions. Some LVs were split between the two disks. With the --partial option, it won't let me see them at all.

I don't want to do that until I've salvaged all the information I can get back. I have plenty of scratch space on other disks. -- Måns Rullgård mru@users.sf.net _______________________________________________ linux-lvm mailing list linux-lvm@sistina.com http://lists.sistina.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
