Hey All,

Unless I'm misunderstanding how to do what I'm trying to do, I'm unable to
destroy a zfs dataset that was cloned and subsequently promoted from
another dataset. Am I doing something wrong?

Log of what I'm doing:

[shawn@shawn-vm-host ~]$ sudo zfs send
rpool/jails/www_template@2013-04-10| sudo zfs recv
tank/jails/www_template/ROOT/base
[shawn@shawn-vm-host ~]$ sudo zfs clone
tank/jails/www_template/ROOT/base@2013-04-10tank/jails/www_template/ROOT/newbe
[shawn@shawn-vm-host ~]$ sudo zfs promote tank/jails/www_template/ROOT/newbe
[shawn@shawn-vm-host ~]$ sudo zfs destroy -r
tank/jails/www_template/ROOT/newbe
cannot destroy 'tank/jails/www_template/ROOT/newbe': filesystem has
dependent clones
use '-R' to destroy the following datasets:
tank/jails/www_template/ROOT/base

uname -a output:

[shawn@shawn-vm-host ~]$ uname -a
FreeBSD shawn-vm-host 10.0-CURRENT FreeBSD 10.0-CURRENT #18

Thanks,

Shawn
