So what you happen to do is manually unmount each ZFS dataset.
That does not mean the ZFS datasets are gone or wont be mounted on the next (re)boot.
As long as the datasets exist and canmount=on, it will get mounted every time.

The easiest fix is to delete the zfs datasets that poudriere created.
You can find the correct dataset with
# zfs list

 And then most probably
# zfs destroy -r zroot/poudriere
