Mark, If you don’t have the patch for LU-5726, then you should definitely try to get that one. If nothing else, reading through the bug report might be useful. It details some of the MDS OOM problems I had and mentions setting vm.zone_reclaim_mode=0. It also has Robin Humble’s suggestion of setting "options libcfs cpu_npartitions=1” (which is something that I started doing as well). -- Rick Mohr Senior HPC System Administrator National Institute for Computational Sciences http://www.nics.tennessee.edu _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
