[Lustre-discuss] Questions about Lustre ACLs

Hi Daniel, I don¹t believe so. Various people have posted informal results from their own tests in the field, but none have ever been formally collated. There are some rough numbers on the Wikipedia page for CFS for GigE, IB, and 10GigE, but they assume particular things about configuration, dis

Stuart, It looks like you have a newer rdac package than sun has on their website. So while your make file builds everything, it ties to install a bit of code that does not exist. FYI. Brock Palen www.umich.edu/~brockp Center for Advanced Computing [EMAIL PROTECTED] (734)936-1985 On Jul

Yes that worked! Thank you very much. Hin't to sun, the 2540 is a very nice array for lustre, it would be good if all the tools with it were checked to work out the box with lustre. Just 2 cents. Brock Palen www.umich.edu/~brockp Center for Advanced Computing [EMAIL PROTECTED] (734)936-19

Hi, I have compiled and used the run rdac driver and my modified makefile is attached. The sequence I've used (perhaps not the best) is: - cd /lib/modules/2.6.9-67.0.7.EL_lustre.1.6.5.1smp/source/ - cp /boot/config-2.6.9-67.0.7.EL_lustre.1.6.5.1smp .config - make clean - make mrp
