Hi all, I have recently been cleaning up Pacemaker's rule code, and came across an inconsistency.
Currently, meta-attributes may have rules with date/time-based expressions (the <date_expression> element). Node attribute expressions (the <expression> element) are not allowed, with the exception of operation meta-attributes (beneath an <op> or <op_defaults> element). I'd like to deprecate support for node attribute expressions for operation meta-attributes in Pacemaker 2.1.8, and drop support in 3.0.0. I don't think it makes sense to vary meta-attributes by node. For example, if a clone monitor has on-fail="block" (to cease all actions on instances everywhere) on one node and on-fail="stop" (to stop all instances everywhere) on another node, what should the cluster do if monitors fail on both nodes? It seems to me that it's more likely to be confusing than helpful. If anyone has a valid use case for node attribute expressions for operation meta-attributes, now is the time to speak up! -- Ken Gaillot <kgail...@redhat.com> _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
