They currently use UFS2 + soft updates (no journaling). I am interested in finding out how the behavior of one of these systems changes if I replace the UFS2 FS where the builds are actually done with a ZFS FS. I would prefer to avoid the need to touch the machine(s) for this exercise, so I'm interested in trying the exercise using the same hardware -- though possibly configured somewhat differently. What would be a good place to start my research? [Caveat: While I've used UFS longer than ... some readers of this message have been alive, I've not administered ZFS before.] Thanks!
