Create test pool upon device files using the various combinations. 50# - Regular pool 51# - Mirror 52# - Raidz 53# 2. Create necessary filesystem and test files. 54# 3. Export the test pool. 55# 4. Remove one or more devices 56# 5. Verify 'zpool import' will handle d/m device successfully. 57# Using the various combinations. 58# - Regular import 59# - Alternate Root Specified 60# It should be succeed with single d/m device upon 'raidz' & 'mirror', 61# but failed against 'regular' or more d/m devices. 62# 6. If import succeed, verify following is true: 63# - The pool shows up under 'zpool list'. 64# - The pool's health should be DEGRADED. 65# - It contains the correct test file 66# 67 68verify_runnable "global" 69 70set -A vdevs "" "mirror" "raidz" 71set -A options "" "-R $ALTER_ROOT" 72 73function cleanup 74{ 75 # recover the vdevs 76 recreate_files 77 78 [[ -d $ALTER_ROOT ]] && \ 79 log_must rm -rf $ALTER_ROOT 80} 81 82function recreate_files 83{ 84 if poolexists "$TESTPOOL1" ; then 85 cleanup_filesystem $TESTPOOL1 $TESTFS 86 destroy_pool $TESTPOOL1 87 fi 88 89 log_must rm -rf $DEVICE_DIR/* 90 typeset i=0 91 while (( i < $MAX_NUM )); do 92 log_must mkfile $FILE_SIZE ${DEVICE_DIR}/${DEVICE_FILE}$i 93 ((i += 1)) 94 done 95} 96 97log_onexit cleanup 98 99log_assert "Verify that import could handle damaged or missing device." 100 101CWD=$PWD 102cd $DEVICE_DIR || log_fail "Unable change directory to $DEVICE_DIR" 103 104checksum1=$(sum $MYTESTFILE | awk '{print $1}') 105 106typeset -i i=0 107typeset -i j=0 108typeset -i count=0 109typeset basedir backup 110 111while (( i < ${#vdevs[*]} )); do 112 113 setup_filesystem "$DEVICE_FILES" \ 114 $TESTPOOL1 $TESTFS $TESTDIR1 \ 115 "" ${vdevs[i]} 116 117 backup="" 118 119 guid=$(get_config $TESTPOOL1 pool_guid) 120 log_must cp $MYTESTFILE $TESTDIR1/$TESTFILE0 121 122 log_must zfs umount $TESTDIR1 123 124 j=0 125 while (( j < ${#options[*]} )); do 126 127 count=0 128 action=log_must 129 130 # 131 # Restore all device files. 132 # 133 [[ -n $backup ]] && \ 134 log_must tar xf $DEVICE_DIR/$DEVICE_ARCHIVE 135 136 for device in $DEVICE_FILES ; do 137 log_must rm -f $device 138 139 poolexists $TESTPOOL1 && \ 140 log_must zpool export $TESTPOOL1 141 142 # 143 # Backup all device files while filesystem prepared. 144 # 145 if [[ -z $backup ]]; then 146 log_must tar cf $DEVICE_DIR/$DEVICE_ARCHIVE \ 147 ${DEVICE_FILE}* 148 backup="true" 149 fi 150 151 (( count = count + 1 )) 152 153 case "${vdevs[i]}" in 154 'mirror') (( count == $GROUP_NUM )) && \ 155 action=log_mustnot 156 ;; 157 'raidz') (( count > 1 )) && \ 158 action=log_mustnot 159 ;; 160 '') action=log_mustnot 161 ;; 162 esac 163 164 typeset target=$TESTPOOL1 165 if (( RANDOM % 2 == 0 )) ; then 166 target=$guid 167 log_note "Import by guid." 168 fi 169 $action zpool import \ 170 -d $DEVICE_DIR ${options[j]} $target 171 172 [[ $action == "log_mustnot" ]] && continue 173 174 log_must poolexists $TESTPOOL1 175 176 health=$(zpool list -H -o health $TESTPOOL1) 177 178 [[ $health == "DEGRADED" ]] || \ 179 log_fail "$TESTPOOL1: Incorrect health($health)" 180 log_must ismounted $TESTPOOL1/$TESTFS 181 182 basedir=$TESTDIR1 183 [[ -n ${options[j]} ]] && \ 184 basedir=$ALTER_ROOT/$TESTDIR1 185 186 [[ ! -e $basedir/$TESTFILE0 ]] && \ 187 log_fail "$basedir/$TESTFILE0 missing after import." 188 189 checksum2=$(sum $basedir/$TESTFILE0 | awk '{print $1}') 190 [[ "$checksum1" != "$checksum2" ]] && \ 191 log_fail "Checksums differ ($checksum1 != $checksum2)" 192 193 done 194 195 ((j = j + 1)) 196 done 197 198 recreate_files 199 200 ((i = i + 1)) 201done 202 203log_pass "Import could handle damaged or missing device." 204
