Create a storage pool. Only use the file vdevs because it is easy to 43# generate checksum errors on them. 44# 2. Mostly fill the pool with data. 45# 3. Corrupt it by DDing to the underlying vdev 46# 4. Verify that the vdev becomes DEGRADED. 47# 5. ONLINE it and verify that it resilvers and joins the pool. 48# 49# TESTABILITY: explicit 50# 51# TEST_AUTOMATION_LEVEL: automated 52# 53# CODING STATUS: COMPLETED (2012-08-09) 54# 55# __stc_assertion_end 56# 57############################################################################### 58 59verify_runnable "global" 60 61VDEV0=${TMPDIR}/file0.${TESTCASE_ID} 62VDEV1=${TMPDIR}/file1.${TESTCASE_ID} 63VDEVS="${VDEV0} ${VDEV1}" 64TESTFILE=/$TESTPOOL/testfile 65VDEV_SIZE=192m 66 67 68function cleanup 69{ 70 destroy_pool $TESTPOOL 71 $RM -f $VDEVS 72} 73 74log_assert "ZFS will degrade a vdev that produces checksum errors" 75 76log_onexit cleanup 77 78log_must create_vdevs $VDEV0 $VDEV1 79ensure_zfsd_running 80for type in "raidz" "mirror"; do 81 log_note "Testing raid type $type" 82 83 create_pool $TESTPOOL $type ${VDEVS} 84 corrupt_pool_vdev $TESTPOOL $VDEV1 $TESTFILE 85 destroy_pool $TESTPOOL 86done 87 88cleanup 89log_pass 90
