I *would* highly recommend ZFS for this kind of application. The ability to dynamically expand the zpool (zpool is the zfs "volume manager") is excellent for these kinds of applications. ZFS on Linux is still a bit.....hmm....young as a filesystem so give it another year perhaps. Its being heavily developed by Lawrence Livermore National Lab at the moment for use with the Lustre Parallel filesystem and so NFS export of ZFS filesystems is still a bit flaky however the core is good and stable now. With RHEL 7 and Centos 7 we shall see btrfs as a native filesystem. This should make this kinda thing extremely easy.
