It may be worth clarification to note GlusterFS is not a cluster
filesystem.  It is a distributed filesystem.  There is a significant
difference between clustered and distributed.

A distributed filesystem such as Gluster is applicable to your needs as
you can add/remove clients in an ad hoc manner without issue.  A cluster
filesystem is probably not suitable, because you simply can't connect
new nodes in a willy nilly fashion.  None of OCFS, GFS, GPFS, CXFS, etc
handle this very well, if at all.  Cluster filesystems require hardware
fencing between nodes.  One doesn't setup hardware fencing willy nilly.
