Hi, We aim for backward compatibility, so this likely is a bug. Can you attach the output of crm_report from around this time? crm_report --from "YYYY-M-D H:M:S" --to "YYYY-M-D H:M:S" FYI, you cannot do a rolling upgrade from corosync 1 to corosync 2, but I believe both 14.04 and 16.04 use corosync 2. _______________________________________________ Users mailing list: Users@clusterlabs.org http://clusterlabs.org/mailman/listinfo/users Project Home: http://www.clusterlabs.org Getting started: http://www.clusterlabs.org/doc/Cluster_from_Scratch.pdf Bugs: http://bugs.clusterlabs.org
