37 | # DESCRIPTION: | |
38 | # Verify that pool imports by same name only have one winner | |
39 | # | |
40 | # STRATEGY: | |
41 | # 1. Create 4 single disk pools with the same name | |
42 | # 2. Generate some ZIL records (for a longer import) | |
43 | # 3. Export the pools | |
44 | # 4. Import the pools in parallel | |
45 | # 5. Repeat with using matching guids | |
46 | # | |
