Yep, LLNL''s mdtest uses MPI for coordination but POSIX for metadata, so the 'pvfs2:' prefix won't work for that test (it works for the mpi-md-test in the PVFS CVS). What version of mdtest are you using? You are giving mdtest the '-d' option? I can't think of a reason for mdtest to ignore your testdir option and start doing stuff in the local directory... ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
