Use a pair of transitional states, "takeover" and "relinquish", when transitioning between primary and secondary coordinator states. This provides a clsuter-wide record that the nodes are still working during their synchronous transition states, and should allow clients to determine when the node(s) have fully switched over. Also add an additional 2 seconds of wait at the end of the transition jobs to ensure everything has had a chance to start before proceeding. References #72
PVC - The Parallel Virtual Cluster suite
PVC is a suite of Python 3 tools to manage virtualized clusters. It provides a fully-functional private cloud based on four key principles:
- Be Free Software Forever (or Bust)
- Be Opinionated and Efficient and Pick The Best Software
- Be Scalable and Redundant but Not Hyperscale
- Be Simple To Use, Configure, and Maintain
It is designed to be an administrator-friendly but extremely powerful and rich modern private cloud system, but without the feature bloat and complexity of tools like OpenStack. With PVC, an administrator can provision, manage, and update a cluster of dozens or more hypervisors running thousands of VMs using a simple CLI tool, HTTP API, or [eventually] web interface. PVC is based entirely on Debian GNU/Linux and Free-and-Open-Source tools, providing the glue to bootstrap, provision and manage the cluster, then getting out of the administrators' way.
Your cloud, the best way; just add physical servers.
