Hi Murali I'm seeing this on chiba with posix ior and the flash io benchmark (oddly enough, just with the parallel netcdf version, not the hdf5 one). I agree it's something related to chiba, but have no idea what it could be. I tried a different version of berkely db and saw the same results. pvfs2-ping works, but pvfs2-ls hangs in getattr. servers don't *appear* to be stuck in anything, but I only hooked up a debugger to the server-that-wouldn't-die. I can reliably get one run of 'flash_io_benchmark' in, no matter how many processes, but after that, nothing. I have to not only restart the servers, but start over from scratch with a new file system for a second run to complete. nope, pvfs2-fsck doesn't show any problems with the file system after I restart the servers. wierd one. ==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
