As I understand Flocker creates ZFS snapshots which are replicated between the nodes. Is this happening continuously and to all nodes? It's not really clear from the post.
- lewq 12y agoHey geku! We are not currently doing continuous replication between nodes, although we are working on a cloud block device backend which would allow synchronous replication using the underlying cloud block service. In particular this would enable stateful failover... is that what you had in mind?
- geku 12y agoYes, that was the point. Thanks for clarification.
- ferrantim 12y agoFlocker doesn't continuously replicate data at this point, but it is something we've considered adding. Today, replication happens only when you migrate the data volume. This blog gives a good step-by-step of what happens when a migration occurs: https://clusterhq.com/blog/deploying-multi-node-elasticsearch-logstash-kibana-cluster-using-docker/ https://clusterhq.com/blog/deploying-multi-node-elasticsearc...
