I worked it out... The Red Hat changelog for 1.1.8-2 originally contained +- Cman is the only supported membership & quorum provider, do not ship the corosync plugin When this decision was reversed (when I realised no-one was seeing the ERROR logs indicating it was going away), I neglected to re-instate the following distro specific patch (which avoided conflicts between the ID used by CMAN and Pacemaker): diff --git a/configure.ac b/configure.ac index a3784d5..dafa9e2 100644 --- a/configure.ac +++ b/configure.ac @@ -1133,7 +1133,7 @@ AC_MSG_CHECKING(for native corosync) COROSYNC_LIBS="" CS_USES_LIBQB=0 -PCMK_SERVICE_ID=9 +PCMK_SERVICE_ID=10 LCRSODIR="$libdir" if test $SUPPORT_CS = no; then So Pacemaker < 6.4 is talking on slot 10, while Pacemaker == 6.4 is using slot 9. This is why the two versions cannot see each other :-( I'm very sorry. _______________________________________________ Pacemaker mailing list: Pacemaker@oss.clusterlabs.org http://oss.clusterlabs.org/mailman/listinfo/pacemaker Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
