Re: [gentoo-user] RAID1 + LVM2 booting screwed up. Help, please!

It turns out I panicked needlessly, since my root partition is on /dev/sdb1. I didn't manage to figure out how to get / onto the LVM2 way back when. I'm glad I didn't delete the trial installation, which I'm renaming to rescue :-). Thanks for the tip. I've a feeling I'll be needing vgchange sometime or other. -- alan dot mckinnon at gmail dot com -- Alan Mackenzie (Nuremberg, Germany).

Press i when prompted, and you should be able to bypass the bad startup item; alternatively, if you have access to grub boot, you can also try booting into single user mode.
