On a recommendation I installed spl/zfs 6.5.9. Looks like the issue was fixed in the chain somewhere between this and 6.5.9. The dataset came back just fine.
That said, before closing out, where can I find Ubuntu 16.04 images? I tried in vain but all I could seem to get my hands on were the updated 16.04.2.
