I'm far from an expert with LVM, but I think the answer is a safe No. And even further, you could possibly recover the data on the damaged drive (see http://grover.open2space.com/node/17). The data stored on that particular drive might become in accessible (without any recovery efforts), but the data sitting on the other drives should still be there. I'm taking a guess based on what I saw during a data recovery process, but... It looks like the drive/partition is tagged as being part of a volume, and then the appropriate file system is applied. If this is the case, then loosing a drive should not corrupt your filesystem on the remaining drives. I am not comfortable enough with my knowledge to say this is anywhere near authoritative. But I do hope I helped... Shawn
