Hi, The development of PVFS2 is quite active [1]. The web site says that "PVFS1 is still being very actively maintained and improved" and that they "will continue to do so until PVFS2 reaches the level of maturity necessary to allow for a smooth transition." [2] [1] See the PVFS2 mailing lists http://www.pvfs.org/pvfs2/lists.html [2] http://www.pvfs.org/pvfs2/pvfs1.html Drew Daniels
