The pacemaker-next schema contains experimental features for testing before potential release. To use these features, someone must explicitly set validate-with in their configuration to pacemaker-next (or its legacy alias, pacemaker-1.1).
There is a feature that has been hanging around in there for a long time: the ability to reference particular instances of a clone in constraints, using "rsc-instance"/"with-rsc-instance" (colocation) or "first-instance"/"then-instance" (ordering). The originally proposed use case (back in 2009) was having separate IP addresses, each associated with one copy of the clone: https://developerbugs.linuxfoundation.org/show_bug.cgi?id=2169 My question is: has anyone used or tested this, or is anyone interested in this? We won't promote it to the default schema unless it is tested. My feeling is that it is more likely to be confusing than helpful, and there are probably ways to achieve any reasonable use case with existing syntax. -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Users mailing list: Users@clusterlabs.org http://lists.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
