Description Sean Cohen 2016-03-13 15:44:51 UTC
Problem description

The existing design is great for some backends, but is challenging for many devices to fit in to. It’s also filled with pitfalls with the question of managed/unmanaged, not to mention trying to deal with failing over some volumes and leaving others. The concept of failing over on a volume basis instead of on a device basis while nice for testing doesn’t fit well into the intended use case and results in quite a bit of complexity and also is not something that a number of backends can even support.

Use Cases

This is intended to be a DR mechanism. The model Use Case is a catastrophic event occurring on the backend storage device, but some or all volumes that were on the primary backend may have been replicated to another backend device in which case those volumes may still be accessible.
