Create N(>3,<5) virtual disk files. # 2. Create raidz2 pool based on the virtual disk files. # 3. Fill the filesystem with directories and files. # 4. Record all the files and directories checksum information. # 5. Damaged at most two of the virtual disk files. # 6. Verify the data is correct to prove raidz2 can withstand 2 devices # are failing. # verify_runnable "global" log_assert "Verify raidz2 pool can withstand two devices are failing." log_onexit cleanup typeset -i cnt=$(random 3 5) setup_test_env $TESTPOOL raidz2 $cnt # # Inject data corruption errors for raidz2 pool # for i in 1 2; do damage_devs $TESTPOOL $i "label" log_must is_data_valid $TESTPOOL log_must clear_errors $TESTPOOL done # # Inject bad devices errors for raidz2 pool # for i in 1 2; do damage_devs $TESTPOOL $i log_must is_data_valid $TESTPOOL log_must recover_bad_missing_devs $TESTPOOL $i done # # Inject missing device errors for raidz2 pool # for i in 1 2; do remove_devs $TESTPOOL $i log_must is_data_valid $TESTPOOL log_must recover_bad_missing_devs $TESTPOOL $i done log_pass "Raidz2 pool can withstand two devices are failing passed."
