That's strictly for KVM, not for OS virtualized instances. So, no this model doesn't work. There's no direct equivalent of a disk. There is a delegated dataset, but that's scoped to the instance itself. You could instead create your own floating delegated dataset and use the zoneadm and zfs tools yourself to manage it. You'll also likely need something inside of the guest to forcibly unount it and mount it on the other side. But you won't be able to manage it with vmadm. > 2) can I then attach (preferably live) the same storage disk to the > partner zone? Again, not a disk, but a zfs file system, presumably. You'd again need logic in the guest or go into the guest to mount it. > And also of great interest (the networking question): > > 3) could we export (for remote attachment) the storage disk over the > network as a block device?

You could instead share it with NFS. But in general, I'd note, this model of trying to build HA doesn't really fit in with the general model of SmartOS. You'll likely find yourself fighting against it, not that it means it's impossible.
