LVM
in [Debian]

From: Gerald C.Catling on 15 Jun 2010 21:40 Many thanks to all that responded to try to solve this LVM problem. I could not recover any data from the crashed system. I could not find any method of mounting drive 2 or 3 as individual drives and the system would not create a volume group without the now non-existant first drive. Once again, many thanks. I will have to try RAID 1. Gerald -- To UNSUBSCRIBE, email to debian-user-REQUEST(a)lists.debian.org with a subject of "unsubscribe". Trouble?

And, there really is nothing wrong with lvm per se, you just have to be careful of having volumes spanning harddrives. Without redundancy, you can lose the volume. best of luck A

I believe (any many would agree, I think) that LVM is the bees' knees, but it should be on top of some sort of RAID. This has already been said, but I think it bears repeating. A RAID 1 for redundancy makes me sleep better at night. It's not perfect, nor foolproof, but it is easy and cheap.
