To be clear, I think there are two things being asked here. One question
is "do I need a dedicated partition/disk for an AFS partition?" The
answer to that is no; you can just create new /vicepX directories, and
create the file /vicepa/AlwaysAttach to use them. If you want to use
some other partition, just bind-mount (or lofs-mount, etc) /vicepa to
The other question is about whether you can use an existing directory
structure of data, which which Lars answered. You can use an
already-existing partition, but you need to copy your data into AFS; you
can't just use it straight from disk.
However, there is jhutz's hostafsd (and tafssrv), which does allow for
serving existing data via AFS. But as far as I know those haven't been
touched in awhile, aren't ready for production use, etc etc.
