This one is still in patch form. Some of our customers are testing it in production now, but it hasn't made its way to any official kernels yet. | | Can I get hotfixes if possible? (el5.6 x64) | | AB If you're a Red Hat customer you should contact our support people. We don't have kernels built for other distros, but as I said, the patches are all posted in various places. The first place to look is the cluster-devel mailing list. The archives are here: https://www.redhat.com/archives/cluster-devel/ The clustered unlink patch is here: https://www.redhat.com/archives/cluster-devel/2011-February/msg00059.html The self-tuning glocks patch is here: https://www.redhat.com/archives/cluster-devel/2011-January/msg00079.html The "large file" slowdown patch only affects RHEL5, so the upstream code and RHEL6 don't have that problem. The rhel5 patch is attached to this bugzilla bug (not sure if it's public or private): https://bugzilla.redhat.com/show_bug.cgi?id=683155 And as for fsck.gfs2, I think the performance patches are planned for RHEL5.7.
