My 1.6.5 here does not report it''s patchless: lustre: 1.6.5 kernel: 47 build: 1.6.5-19691231190000-PRISTINE-.cache.OLDRPMS.20080513015618.linux-smp-2.6.9-67.0.7.EL_lustre.1.6.5.i686-2.6.9-67.0.7.EL_lustre.1.6.5smp If you are using our kernel on your MDS/OSS and it''s reporting patchless, this indeed is a bug.

In the context here, "patchless" means "no VFS patches" and that "clients can run on patchless kernels". This has nothing to do with whether the kernel has any of our patches on it. Any server kernel HAS to have patches in order to run. The fact that your kernel reports a "kernel: 47" is because that is the version of the VFS patch API that is being used on your RHEL4 2.6.9 kernel. Newer kernels (RHEL5, SLES10, vanilla 2.6.16+) will report "patchless" here. Cheers, Andreas -- Andreas Dilger Sr. Staff Engineer, Lustre Group Sun Microsystems of Canada, Inc.

Hi Andreas, Thanks for the explanation. I actually sent my response, and created bug 16516, before you sent your response, but my posting was delayed by the list moderator since I am not a list subscriber. I modifed the bug to request that the wording of the program output be changed to something like: kernel: no VFS patches This could reduce the confusion that Brian and I and probably others would have with the current wording.
