Create test pool upon device files using the various combinations. 49# - Regular pool 50# - Mirror 51# - Raidz 52# 2. Create necessary filesystem and test files. 53# 3. Export the test pool. 54# 4. Remove one or more devices 55# 5. Verify 'zpool import' will handle d/m device successfully. 56# Using the various combinations. 57# - Regular import 58# - Alternate Root Specified 59# It should be succeed with single d/m device upon 'raidz' & 'mirror', 60# but failed against 'regular' or more d/m devices. 61# 6. If import succeed, verify following is true: 62# - The pool shows up under 'zpool list'. 63# - The pool's health should be DEGRADED. 64# - It contains the correct test file 65# 66# TESTABILITY: explicit 67# 68# TEST_AUTOMATION_LEVEL: automated 69# 70# CODING_STATUS: COMPLETED (2005-08-01) 71# 72# __stc_assertion_end 73# 74################################################################################ 75 76verify_runnable "global" 77 78set -A vdevs "" "mirror" "raidz" 79set -A options "" "-R $ALTER_ROOT" 80 81function perform_inner_test 82{ 83 typeset action=$1 84 typeset import_opts=$2 85 typeset target=$3 86 typeset basedir 87 88 $action $ZPOOL import -d $DEVICE_DIR ${import_opts} $target 89 [[ $action == "log_mustnot" ]] && return 90 91 log_must poolexists $TESTPOOL1 92 93 health=$($ZPOOL list -H -o health $TESTPOOL1) 94 [[ "$health" == "DEGRADED" ]] || \ 95 log_fail "ERROR: $TESTPOOL1: Incorrect health '$health'" 96 log_must ismounted $TESTPOOL1/$TESTFS 97 98 basedir=$TESTDIR1 99 [[ -n "${import_opts}" ]] && basedir=$ALTER_ROOT/$TESTDIR1 100 [[ ! -e "$basedir/$TESTFILE0" ]] && \ 101 log_fail "ERROR: $basedir/$TESTFILE0 missing after import." 102 103 checksum2=$($SUM $basedir/$TESTFILE0 | $AWK '{print $1}') 104 [[ "$checksum1" != "$checksum2" ]] && \ 105 log_fail "ERROR: Checksums differ ($checksum1 != $checksum2)" 106 107 log_must $ZPOOL export $TESTPOOL1 108} 109 110log_onexit cleanup_missing 111 112log_assert "Verify that import could handle damaged or missing device." 113 114CWD=$PWD 115cd $DEVICE_DIR || log_fail "ERROR: Unable change directory to $DEVICE_DIR" 116 117checksum1=$($SUM $MYTESTFILE | $AWK '{print $1}') 118 119typeset -i i=0 120while :; do 121 typeset vdtype="${vdevs[i]}" 122 123 typeset -i j=0 124 while (( j < ${#options[*]} )); do 125 typeset opts="${options[j]}" 126 [ -n "$vdtype" ] && typestr="$vdtype" || typestr="stripe" 127 128 # Prepare the pool. 129 setup_missing_test_pool $vdtype 130 guid=$(get_config $TESTPOOL1 pool_guid $DEVICE_DIR) 131 log_note "*** Testing $typestr tvd guid $guid opts '${opts}'" 132 133 typeset -i count=0 134 for device in $DEVICE_FILES ; do 135 log_mustnot poolexists $TESTPOOL1 136 log_must $RM -f $device 137 138 (( count = count + 1 )) 139 140 action=log_must 141 case "$vdtype" in 142 'mirror') (( count == $GROUP_NUM )) && \ 143 action=log_mustnot 144 ;; 145 'raidz') (( count > 1 )) && \ 146 action=log_mustnot 147 ;; 148 '') action=log_mustnot 149 ;; 150 esac 151 152 log_note "Testing import by name; ${count} removed." 153 perform_inner_test $action "${opts}" $TESTPOOL1 154 155 log_note "Testing import by GUID; ${count} removed." 156 perform_inner_test $action "${opts}" $guid 157 done 158 159 recreate_missing_files 160 (( j = j + 1 )) 161 done 162 (( i = i + 1 )) 163 (( i == ${#vdevs[*]} )) && break 164done 165 166log_pass "Import could handle damaged or missing device." 167
