Ah, OK.. if you are bypassing the kernel, try the 'pvfs2-xattr' utility. If the 'setfattr' way looks like this: setfattr -n 'usr.pvfs2.num_dfiles' -v '1' /mnt/pvfs2/dir_ss1 the 'pvfs2-xattr' way looks like this: pvfs2-xattr -s -k 'usr.pvfs2.num_dfiles' -v '1' /mnt/pvfs2/dir_ss1 By the way, the 'pvfs2:' prefix only works for ROMIO (MPI-IO) applications. ==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
