If we wanted to do that I'd have figured out how to bring HAST into the mix but HAST+ZFS is very messy. However, if a head unit completely died we'd just connect the JBODs to the other head unit and import the pool (you can daisy-chain them if you're out of ports on the controller). However, we do as a general rule stay under 50% storage so if we really needed to we could move all data to the other server without customers knowing, perform maintenance, and move data back.
