37 # DESCRIPTION: | |
38 # Once a pool has been exported, and one or more devices are | |
39 # damaged or missing (d/m), import should handle this kind of situation | |
40 # as described: | |
41 # - Regular, report error while any number of devices failing. | |
42 # - Mirror could withstand (N-1) devices failing | |
43 # before data integrity is compromised | |
44 # - Raidz could withstand one devices failing | |
45 # before data integrity is compromised | |
46 # Verify those are true. | |
47 # | |
48 # STRATEGY: | |
49 # 1. Create test pool upon device files using the various combinations. | |
50 # - Regular pool | |
51 # - Mirror | |
52 # - Raidz | |
53 # 2. Create necessary filesystem and test files. | |
54 # 3. Export the test pool. | |
55 # 4. Remove one or more devices | |
56 # 5. Verify 'zpool import' will handle d/m device successfully. | |
57 # Using the various combinations. | |
58 # - Regular import | |
59 # - Alternate Root Specified | |
60 # It should be succeed with single d/m device upon 'raidz' & 'mirror', | |
61 # but failed against 'regular' or more d/m devices. | |
62 # 6. If import succeed, verify following is true: | |
63 # - The pool shows up under 'zpool list'. | |
64 # - The pool's health should be DEGRADED. | |
65 # - It contains the correct test file | |
66 # | |
