Create a storage pool with a hotspare. Only use the file vdevs because 43# it is easy to generate checksum errors on them. 44# 2. fault a vdev to active the hotspare 45# 3. Mostly fill the pool with data. 46# 4. Corrupt it by DDing to the hotspare's underlying file. 47# 5. Verify that the hotspare becomes DEGRADED. 48# 6. 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 (2014-05-13) 55# 56# __stc_assertion_end 57# 58############################################################################### 59 60verify_runnable "global" 61 62VDEV0=${TMPDIR}/file0.${TESTCASE_ID} 63VDEV1=${TMPDIR}/file1.${TESTCASE_ID} 64SPARE_VDEV=${TMPDIR}/file2.${TESTCASE_ID} 65BASIC_VDEVS="${VDEV0} ${VDEV1}" 66VDEVS="${BASIC_VDEVS} ${SPARE_VDEV}" 67TESTFILE=/$TESTPOOL/testfile 68VDEV_SIZE=192m 69 70 71function cleanup 72{ 73 destroy_pool $TESTPOOL 74 $RM -f $VDEVS 75} 76 77log_assert "ZFS will degrade a spare vdev that produces checksum errors" 78 79log_onexit cleanup 80 81ensure_zfsd_running 82log_must create_vdevs $VDEV0 $VDEV1 $SPARE_VDEV 83 84for type in "mirror" "raidz"; do 85 log_note "Testing raid type $type" 86 87 create_pool $TESTPOOL $type ${BASIC_VDEVS} spare ${SPARE_VDEV} 88 89 # Activate the hotspare 90 $ZINJECT -d ${VDEV0} -A fault $TESTPOOL 91 92 # ZFSD can take up to 60 seconds to replace a failed device 93 # (though it's usually faster). 94 wait_for_pool_dev_state_change 60 $SPARE_VDEV INUSE 95 96 corrupt_pool_vdev $TESTPOOL $SPARE_VDEV $TESTFILE 97 destroy_pool $TESTPOOL 98done 99 100cleanup 101log_pass 102
