And this is why I don't like LVM to begin with. If one of the drives dies, you're screwed not only for the data on that drive, but even for data on remaining healthy drives. I never really saw the point of LVM. Storing data on plain physical partitions, having an intelligent directory structure and a few wise well-placed symlinks across the drives can go a long way in having flexible storage, which is way more robust than LVM. With today's huge drive capacities, I really see no reason to adjust the sizes of partitions on-the-fly, and putting several TB of data in a single directory is just Bad Design to begin with. That said, if you have a multi-TB amount of critical data while not having at least a simple RAID-1 backup, you are already standing in a big pile of sh*t just waiting to become obvious, regardless of LVM and stuff. Hardware fails, and storing data without a backup is just simply a disaster waiting to happen. Best, :-) Marko
