As I learned, the reiserfs does not have the inode-abstraction that is
needed for a proper functioning of AFS. The ext2 as well as ext3 does. 

There were some definite warnings about using reiserfs on this list.

Hmm. I recently read a review of different journaling fs for linux. It
stated that most journaling fs only work on the metadata, not on the
content of the files. Probably, the AFS client did not like the
content of your files, then? 

A simple "rm -rf /usr/vice/cache/*" should have helped then.

IIRC, ext3 has an option to log the file contents as well. I don't
remember precisely, I will check that this at home.
