Matthew Dillon answered some mailing list questions on how clustering and data copies will work in HAMMER2 – no due date, of course, because this is very complex. If you’re really into it, there’s always watching the recent commits.

How can i install/use hammer2?
It’s in DragonFly-current.. Install from a snapshot and keep tracking it.
Note that HAMMER2 is not done . You can create disks and access them from another computer, but there’s no hardlink mechanism and no way to handle multiple hosts, for example. I.e. don’t use it with any data you want to have survive. Developing it with code is the only reason to run it right now.
