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...
