# DESCRIPTION:
# 'zfs destroy -r|-rf|-R|-Rf <fs|ctr|vol|snap>' should recursively destroy
# all children and clones based on options.
#
# STRATEGY:
# 1. Create test environment according to options. There are three test
# models can be created. Only ctr, fs & vol; with snap; with clone.
# 2. According to option, make the dataset busy or not.
# 3. Run 'zfs destroy [-rRf] <dataset>'
# 4. According to dataset and option, check if get the expected results.
#
verify_runnable "both"
#
# According to parameters, 1st, create suitable testing environment. 2nd,
# run 'zfs destroy $opt <dataset>'. 3rd, check the system status.
#
# $1 option of 'zfs destroy'
# $2 dataset will be destroyed.
