2 Node High Availability cluster for nats stream

[msg2man]

I need to create a HA cluster for nats jetstream, my limitations are:-

• only 2 nodes are there, hence using the standard nats streaming cluster with odd number of nodes (to achieve raft quorum) is not possible.
• there is no shared storage between both the nodes or a common nfs mount, so using a fault tolerance nats cluster is also not possible.

So is there a better way of achieving the HA clustering with 2 nodes, or explicitly rsyncing the stream store periodically to the standby node would be the only way for this ?

Thank you.

For JetStream and a 2-node system you have data durability but if any of the servers has an issue the system and all streams will be blocked until both servers are back and running.
