So, a completely unrelated bug with Windows and ACPI took down my machine while the VM was running. After some tomfoolery to get filesystems cleaned back up again, I tried what you suggested... curie# zfs unmount tank curie# zfs mount tank curie# zfs snapshot tank@snap1 curie# Poof! Success! At least at making snapshots. Of course, I don't yet see a "Previous Versions" tab in the properties of anything yet (which I do see on some other shares from other servers). But at least now I can fool with those a bit. Thanks Bob!
