36 | # DESCRIPTION: | |
37 | # A zvol volume will return ENOSPC when the underlying pool runs out of | |
38 | # space. | |
39 | # | |
40 | # STRATEGY: | |
41 | # 1. Create a pool | |
42 | # 2. Create a zvol volume | |
43 | # 3. Create a ufs file system ontop of the zvol | |
44 | # 4. Mount the ufs file system | |
45 | # 5. Fill volume until ENOSPC is returned | |
46 | # | |
