I’m looking for a simple way to replicate data within a cluster. It looks like my resources will be self-configuring and may need to push changes they see to all nodes in the cluster. The idea being that when a node crashes, the resource will have its configuration present on the node on which it is restarted. We’re talking about a few kb of data, probably in one file, probably text. A typical cluster would have multiple resources (more than two), one resource per node and one extra node. Ideas? Could I use the CIB directly to replicate data? Use cibadmin to update something and sync? How big can a resource parameter be? Could a resource modify its parameters so that they are replicated throughout the cluster? Is there a simple file replication Resource Agent? Drdb seems like overkill. Regards. May you live in interesting times, may you come to the attention of important people and may all your wishes come true.
