| # 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. |
