I'm a noob, but IIUC this is the option giving the best performance:

Clients can write to both servers in parallel and read scattered (read
performance using multiple files ~ 16x vs 2x with a single disk per
host). Moreover it's easier to extend.
But why ZFS instead of XFS ? In my experience it's heavier.

PS: add a third host ASAP, at least for arbiter volumes (replica 3
arbiter 1). Split brain can be a real pain to fix!
