Are we talking about block-level clustering underneath ZFS (e.g. HAST or ${somethingElse}) or otherwise incorporated into ZFS itself at some low level? If you Google for “High-availability ZFS” you will encounter things like RSF-1 or the somewhat more mysterious Zetavault (http://www.zeta.systems/zetavault/high-availability/) but it’s not entirely clear how these technologies work, they simply claim to “scale-out ZFS” or “cluster ZFS” (which can be done within ZFS or one level above and still probably pass the Marketing Test for what people are willing to put on a web page). umm look at Panzura who have been selling this on FreeBSD for 4 years and need FreeBSD devs in the bay area (or closer than me))
