as you say, the md rebuild bug is in all kernels < 2.6.32 http://marc.info/?l=linux-raid&m=130192650924540&w=2 the Whamcloud fix is LU-824 which landed in git a tad after 1.8.7-wc1. I also asked RedHat nicely, and they added the same patch to RHEL5.8 kernels, which IMHO is the correct place for a fundamental md fix. so once Lustre supports RHEL5.8 servers, then the patch in Lustre isn't needed any more. cheers, robin -- Dr Robin Humble, HPC Systems Analyst, NCI National Facility _______________________________________________ Lustre-discuss mailing list Lustre-discuss@lists.lustre.org http://lists.lustre.org/mailman/listinfo/lustre-discuss
