[OpenAFS] Which file system is the best for AFS data partitions?

I use ext3 with noatime for vice partitions and try to limit servers to 
less than 2 TB per server for servers housing research data and .5 TB per 
server for servers housing home volumes. This has worked well so far.

Outside AFS, I use xfs for filesystems over 2 TB, but as I said, I 
currently try to limit each server to no more than 2 TB. When/if I have 
more than a few TBs per server, I'd probably use xfs. ext3 is exponentially 
painful as the size increases.

My $0.02.

Cheers, Stephen
