Thats correct. > Also, I have the new intel 8 core cpu's and would prefer to go to sles 11 sp > 1 instead of sles 11. However, this is not supported by the lustre client > yet.

Its been a while since I made the RPMs, but I found this laying around: ./configure --disable-server --with-linux=/usr/src/linux-2.6.22-pfm-xeon --with-o2ib --enable-quota --disable-readline Then I believe 'make rpms' does the right thing. Now that I said how easy it was, there is a caveat. Now, there may be issues with specific kernels, but this worked for us. The linux-2.6.22 kernel is a kernel.org kernel with pfm patches (performance monitoring) and this kernel also has a NDAed patch from AMD because there are bugs in the CPUs and the patches are workarounds for the bugs in the CPU. It works for us, YMMV. -mb -- +----------------------------------------------- | Michael Barnes | | Thomas Jefferson National Accelerator Facility | Scientific Computing Group | 12000 Jefferson Ave. | Newport News, VA 23606 | (757) 269-7634 +----------------------------------------------- _______________________________________________ Lustre-discuss mailing list [email protected] http://lists.lustre.org/mailman/listinfo/lustre-discuss
