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...
