LVM does not and should not provide data integrity features. You lost a drive. The data on it goes away. What did you expect would happen? That the data on it would magically reconstruct itself? In a situation like that, losing a drive with LVM is only slightly more inconvenient (one or two more steps) than losing the same drive without LVM (which is horribly inconvenient by itself). Please don't blame LVM for what is actually a user error. -- alan dot mckinnon at gmail dot com
