Create a storage pool. Only use the file vdevs because it is easy to 44# generate checksum errors on them. 45# 2. Mostly fill the pool with data. 46# 3. Corrupt it by DDing to the underlying vdev 47# 4. Verify that the vdev becomes DEGRADED. 48# 5. ONLINE it and verify that it resilvers and joins the pool. 49# 50# TESTABILITY: explicit 51# 52# TEST_AUTOMATION_LEVEL: automated 53# 54# CODING STATUS: COMPLETED (2012-08-09) 55# 56# __stc_assertion_end 57# 58############################################################################### 59 60verify_runnable "global" 61 62VDEV0=${TMPDIR}/file0.${TESTCASE_ID} 63VDEV1=${TMPDIR}/file1.${TESTCASE_ID} 64VDEVS="${VDEV0} ${VDEV1}" 65TESTFILE=/$TESTPOOL/testfile 66VDEV_SIZE=192m 67 68 69function cleanup 70{ 71 destroy_pool $TESTPOOL 72 $RM -f $VDEVS 73} 74 75log_assert "ZFS will degrade a vdev that produces checksum errors" 76 77log_onexit cleanup 78 79log_must create_vdevs $VDEV0 $VDEV1 80ensure_zfsd_running 81for type in "raidz" "mirror"; do 82 log_note "Testing raid type $type" 83 84 create_pool $TESTPOOL $type ${VDEVS} 85 corrupt_pool_vdev $TESTPOOL $VDEV1 $TESTFILE 86 destroy_pool $TESTPOOL 87done 88 89cleanup 90log_pass 91
