Create N(>3,<5) virtual disk files. 40# 2. Create raidz2 pool based on the virtual disk files. 41# 3. Fill the filesystem with directories and files. 42# 4. Record all the files and directories checksum information. 43# 5. Damaged at most two of the virtual disk files. 44# 6. Verify the data is correct to prove raidz2 can withstand 2 devices 45# are failing. 46# 47# TESTABILITY: explicit 48# 49# TEST_AUTOMATION_LEVEL: automated 50# 51# CODING_STATUS: COMPLETED (2006-08-21) 52# 53# __stc_assertion_end 54# 55################################################################################ 56 57verify_runnable "global" 58 59log_assert "Verify raidz2 pool can withstand two devices are failing." 60log_onexit cleanup 61 62for cnt in 3 4; do 63 setup_test_env $TESTPOOL raidz2 $cnt 64 65 # 66 # Inject data corruption errors for raidz2 pool 67 # 68 for i in 1 2; do 69 damage_devs $TESTPOOL $i "label" 70 log_must is_data_valid $TESTPOOL 71 log_must clear_errors $TESTPOOL 72 done 73 74 # 75 # Inject bad devices errors for raidz2 pool 76 # 77 for i in 1 2; do 78 damage_devs $TESTPOOL $i 79 log_must is_data_valid $TESTPOOL 80 log_must recover_bad_missing_devs $TESTPOOL $i 81 done 82 83 # 84 # Inject missing device errors for raidz2 pool 85 # 86 for i in 1 2; do 87 remove_devs $TESTPOOL $i 88 log_must is_data_valid $TESTPOOL 89 log_must recover_bad_missing_devs $TESTPOOL $i 90 done 91done 92 93log_pass "Raidz2 pool can withstand two devices are failing passed." 94
