I think the larger question is: when will ZFS be stable enough that Oracle will say that libzfs is an officially supported interface? Once that happens it will probably be possible for third parties to start accessing ZFS in ways other than the POSIX interface. I'm guessing that support for crypto, device removal, and parity changing (RAID-Z1 <-> Z2 <-> Z3) need to be put in first (the latter two necessitating bp rewrite). I would hazard to guess it will be at least a year before it's even considered and longer before it happens (Solaris 12? or maybe a latter update of Solaris 11?). Until that happens we'll be stuck with working at the ZPL for most things. _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
