All targetcli-fb really does is make interacting with LIO much easier. But you could theoretically roll your own LIO commands, since the interface is sysfs. Targetcli-fb is in python, and quite user-friendly IMHO. SCST is still around, but I believe it's user-space only. (Forgive me if I'm wrong here, but it's been a while since I looked at SCST.) I'd suggest using something like btrfs instead of zfs, since btrfs is getting much better now -- even Debian has taken the hint from SUSE and started using it. :) Check out the "Kernel Target Devel" list (target-devel at vger). Much of the kernel target development recently has been to include other non-iSCSI target support IMHO. There is also a cool new extension to targetcli called tcmu-runner, that allows you to add new functionality to targetcli without having to hack on the kernel. -- Lee Duncan
