+You need to distinguish between the filesystem used by the file server to store the actual AFS data (by convention in /vicep?) and the filesystem used by the client cache manager to cache files.
+
+With the new namei file server you can basically use any filesystem you want. Tne namei file server does not do any fancy stuff behind the scenes but only accesses normal files (their names are a bit strange though).
+
+It is a different story with the old inode based server. It directly operates on the inodes of the underlying file system which therefore has to fully support the inode abstraction scheme. The the Administrators Guide for more details (they differ from system to system).
+
+On the client side, you always have to use a file system supporting the inode abstraction for the cache (usually /usr/vice/cache) since the cache manager references files by their inode. Fortunately, it does not do such tricky stuff as the inode based server. The following file systems have been reported _not_ to work:
+
+- reiserfs
+- vxfs (HP-UX)

+The following file systems have been reported to work for the AFS client cache:

+- ext2
+- ext3
+- hfs (HP-UX)
+- xfs (at least on IRIX 6.5)
