Hi, I've been searching for the answer to this question but can't find a definitive answer. If I set "copies=2" on a dataset after I've written some files, will those older files get multiple copies after a scrub operation?
The main reason I ask is that I'd like to set multiple copies on my root filesystems, which generally get installed via Jumpstart. Jumpstart has no provision for setting ZFS properties when it creates pools, so things like compression just aren't useful yet. However, for systems where there is only one physical drive for the OS, being able to activate multiple copies of user data in a finish script would be really nice. Then I could just kick off a scrub before the server goes into production, and be assured that my root dataset has ditto blocks throughout. If that is indeed the case and I can start using ditto blocks, the next question becomes, "what happens when I use Live Upgrade?" Will the "copies=2" property be preserved during the snapshot/clone process?
