A pool created by a FreeBSD 9 system was imported into FreeBSD 10.1 but
failed to create the recursive mountpoints as shown below.
What's especially interesting is that the free space reported by
zpool(1) and zfs(1) are wildly different, even though there are no
reservations.
Note that I was able to do a zpool upgrade, but that zfs upgrade failed
on the children datasets.
