ouch. Looks like something is wrong with your lvm metadata. Could you confirm that your setup is lvm on top of local RAID, and that there isn't anything else involved (shared storage for example). As a test, I would boot off an LVM enabled live cd and see if the volumes are accessible. That will determine if the problem lies with lvm, your volumes, or with how your gentoo is set up. Last time I looked, the Sistina web site and redhat.com has loads of very useful info and FAQs. If you haven't already, I recommend you get onto those sites and start reading and doing non-destructive tests, as lvm errors can be varied and interesting when stuff goes wrong -- Alan McKinnon alan dot mckinnon at gmail dot com -- gentoo-user@lists.gentoo.org mailing list
