I was wondering if it's possible to to create a DRBD resource on top of another
one without using the stacked configuration options. I would like to establish
a Protocol A with Proxy between node-b and node-c. This will be over a WAN.
Then I want to establish a Protocol C between node-a and node-b. node-a will
know nothing about the proxy or node-c. When I create the resource on node-b
that syncs with node-a I will simply use the resource already established to
sync with node-c. My goal is to make node-a operate as efficient as possible
without the connection to node-c slowing it down.
That is an interesting scenario for sure, but it seems you have designed a
split brain scenario, and that's bad. The hole I see is what if node b is
primary on Cluster A, but secondary on Cluster B, you are now pushing BAD data
onto the Primary in Cluster A, and have just trashed all your data. I may be
misinterpreting your use of the term Proxy, but I don't see how to maintain
consistency.
