LVM is _not_ RAID. It does offer mirroring, if you initially set it up
that way, but other than that, LVM is a lot like the game Jenga: pull
the wrong disk from the setup, and the whole thing collapses. At this
point, all you can do is replace the drive, and restore from backup. You
do keep an up-to-date backup, don't you? If not, consider that lesson
learned #2. :)
