Can I get an explanation of the replication feature? Is this feature specific to your product or are you using DRBD? If using DRBD, can I replicate data between other DRBD systems?
Yes we have this setup to reserve .12 GB space for replication and Initialization for iSCSI volumes so this would seem in many ways proprietary. I know you have good reason for your question we just did not focus our engineering efforts to support outside of what we have built.
