Murali pointed out that if you do all these shm commands as root once, you can then do them as regular users. I'll add this to the faq: if you are running pvfs2-server as a non-root user and get "resource temporarily unavailable", run as root once, then run as a non-root user. Since I had no problems on my workstation (where I have no root access), perhaps lain's restrictive permissions on SysV shared memory is not common? ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Labs, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-developers mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-developers
