AFS has a strong reputation for reliability, and it is
also the oldest of the systems mentioned, having been used widely in
university and corporate settings for years. However I am not
acquainted with its reliability or performance under XFS.
As to why there are so many projects in this area, I suspect a number
of reasons, including different design goals, some projects being
newer than others (the desire for a "fresh start" with a different
approach to the design), etc.
If you dig back in the xfs list archives, you should find some references to
open AFS. Someone, I cannot remember who, got it all working and made
patches available. AFS does have XFS support built in, but it is Irix XFS
support getting linux XFS going required some work.
