Create N(>2,<5) virtual disk files. 40# 2. Create mirror 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 N-1 of the virtual disk files. 44# 6. Verify the data are correct to prove mirror can withstand N-1 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 mirrored pool can withstand N-1 devices are failing or missing." 60log_onexit cleanup 61 62for cnt in 3 2; do 63 typeset -i i=1 64 65 setup_test_env $TESTPOOL mirror $cnt 66 67 # 68 # Inject data corruption errors for mirrored pool 69 # 70 while (( i < cnt )); do 71 damage_devs $TESTPOOL $i "label" 72 log_must is_data_valid $TESTPOOL 73 log_must clear_errors $TESTPOOL 74 75 (( i +=1 )) 76 done 77 78 # 79 # Inject bad devices errors for mirrored pool 80 # 81 i=1 82 while (( i < cnt )); do 83 damage_devs $TESTPOOL $i 84 log_must is_data_valid $TESTPOOL 85 log_must recover_bad_missing_devs $TESTPOOL $i 86 87 (( i +=1 )) 88 done 89 90 # 91 # Inject missing device errors for mirrored pool 92 # 93 i=1 94 while (( i < cnt )); do 95 remove_devs $TESTPOOL $i 96 log_must is_data_valid $TESTPOOL 97 log_must recover_bad_missing_devs $TESTPOOL $i 98 99 (( i +=1 )) 100 done 101done 102 103log_pass "Mirrored pool can withstand N-1 devices failing as expected." 104
