Nice, I'll be doing things the old school 'hard' way by not using the new API setup methods as iirc it expects ZFS to be used and would break if it isn't? Is that still the case?
Either way I've a good workflow for setting everything up the old fashion way should be rather painless.
It doesn't require ZFS to use haf_api_node, so I strongly recommend you use the stack, even if you don't use ZFS. One of our internal systems doesn't have ZFS installed and it still uses the stack without any problems. It just can't use the scripts for taking snapshots and creating the initial directory hierarchy.
Sweet, I'll give it a go then!
