I was just wondering... what happens if one of the drives in the lvm array goes dead?
That can be a problem, depending how your LVM is configured. If you have a logical volume that spans multiple disk drives, then the file system on that volume can get corrupted and/or unreadable/unwriteable. So it's generally a bad idea to do that. Your options around this are either: * make every physical disk be its own volume group, thereby ensuring that no logical volume can span more than one disk. (I do this on my machines, and this works fine for my personal needs, where I only need relatively small amounts of storage. But this wouldn't work for large-scale situations such as where you're trying to create huge virtual disks with multiple terabytes of storage.) * use a raid array as the physical volume underlying a volume group. The redundancy of the raid array would guarantee that the physical storage would still be accessible even if one of the disk drives in the array died. People who use LVM in hard-core, large-scale operations usually go this route. HTH, DR
