Create a storage pool with a hotspare. Only use the file vdevs because 44# it is easy to generate checksum errors on them. 45# 2. fault a vdev to active the hotspare 46# 3. Mostly fill the pool with data. 47# 4. Corrupt it by DDing to the hotspare's underlying file. 48# 5. Verify that the hotspare becomes DEGRADED. 49# 6. ONLINE it and verify that it resilvers and joins the pool. 50# 51# TESTABILITY: explicit 52# 53# TEST_AUTOMATION_LEVEL: automated 54# 55# CODING STATUS: COMPLETED (2014-05-13) 56# 57# __stc_assertion_end 58# 59############################################################################### 60 61verify_runnable "global" 62 63VDEV0=${TMPDIR}/file0.${TESTCASE_ID} 64VDEV1=${TMPDIR}/file1.${TESTCASE_ID} 65SPARE_VDEV=${TMPDIR}/file2.${TESTCASE_ID} 66BASIC_VDEVS="${VDEV0} ${VDEV1}" 67VDEVS="${BASIC_VDEVS} ${SPARE_VDEV}" 68TESTFILE=/$TESTPOOL/testfile 69VDEV_SIZE=192m 70 71 72function cleanup 73{ 74 destroy_pool $TESTPOOL 75 $RM -f $VDEVS 76} 77 78log_assert "ZFS will degrade a spare vdev that produces checksum errors" 79 80log_onexit cleanup 81 82ensure_zfsd_running 83log_must create_vdevs $VDEV0 $VDEV1 $SPARE_VDEV 84 85for type in "mirror" "raidz"; do 86 log_note "Testing raid type $type" 87 88 create_pool $TESTPOOL $type ${BASIC_VDEVS} spare ${SPARE_VDEV} 89 90 # Activate the hotspare 91 $ZINJECT -d ${VDEV0} -A fault $TESTPOOL 92 93 # ZFSD can take up to 60 seconds to replace a failed device 94 # (though it's usually faster). 95 wait_for_pool_dev_state_change 60 $SPARE_VDEV INUSE 96 97 corrupt_pool_vdev $TESTPOOL $SPARE_VDEV $TESTFILE 98 destroy_pool $TESTPOOL 99done 100 101cleanup 102log_pass 103
