Folks, The tiny clustering software that OCFS2 uses these days, O2CB, has had a userspace<->kernel change. The new interface uses usysfs instead of ioctl(2). You will need revision 2006 of ocfs2 and revision 668 of ocfs2-tools. The two revisions go together. Starting the clustering software with /etc/init.d/o2cb works just as before.
