I'd second the use of ext2 for AFS cache because you can allways wipe
and start over with an empty cache partition. During a crash, the
transactions that were not written to the server yet are lost anyway.

How big a cache do you need for your web server? Maybe stripe/mirror
would do much better than RAID5.
