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 succeed with single d/m device upon 'raidz', 'mirror', 61# 'draid' 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 70# Randomly test a subset of combinations to speed up the test. 71(( rc=RANDOM % 3 )) 72if [[ $rc == 0 ]] ; then 73 set -A vdevs "" "mirror" "raidz" 74elif [[ $rc == 1 ]] ; then 75 set -A vdevs "" "mirror" "draid" 76else 77 set -A vdevs "" "raidz" "draid" 78fi 79 80set -A options "" "-R $ALTER_ROOT" 81 82function cleanup 83{ 84 # recover the vdevs 85 recreate_files 86 87 [[ -d $ALTER_ROOT ]] && \ 88 log_must rm -rf $ALTER_ROOT 89} 90 91function recreate_files 92{ 93 if poolexists "$TESTPOOL1" ; then 94 cleanup_filesystem $TESTPOOL1 $TESTFS 95 destroy_pool $TESTPOOL1 96 fi 97 98 log_must rm -rf $DEVICE_DIR/* 99 typeset i=0 100 while (( i < $MAX_NUM )); do 101 log_must rm -f ${DEVICE_DIR}/${DEVICE_FILE}$i 102 log_must truncate -s $FILE_SIZE ${DEVICE_DIR}/${DEVICE_FILE}$i 103 ((i += 1)) 104 done 105} 106 107log_onexit cleanup 108 109log_assert "Verify that import could handle damaged or missing device." 110 111CWD=$PWD 112cd $DEVICE_DIR || log_fail "Unable change directory to $DEVICE_DIR" 113 114read -r checksum1 _ < <(cksum $MYTESTFILE) 115 116typeset -i i=0 117typeset -i j=0 118typeset -i count=0 119typeset basedir backup 120 121while (( i < ${#vdevs[*]} )); do 122 123 setup_filesystem "$DEVICE_FILES" \ 124 $TESTPOOL1 $TESTFS $TESTDIR1 \ 125 "" ${vdevs[i]} 126 127 backup="" 128 129 guid=$(get_config $TESTPOOL1 pool_guid) 130 log_must cp $MYTESTFILE $TESTDIR1/$TESTFILE0 131 132 log_must zfs umount $TESTDIR1 133 134 j=0 135 while (( j < ${#options[*]} )); do 136 137 count=0 138 action=log_must 139 140 # 141 # Restore all device files. 142 # 143 [[ -n $backup ]] && \ 144 log_must tar xf $DEVICE_DIR/$DEVICE_ARCHIVE 145 146 for device in $DEVICE_FILES ; do 147 log_must rm -f $device 148 149 poolexists $TESTPOOL1 && \ 150 log_must zpool export $TESTPOOL1 151 152 # 153 # Backup all device files while filesystem prepared. 154 # 155 if [[ -z $backup ]]; then 156 log_must tar cf $DEVICE_DIR/$DEVICE_ARCHIVE \ 157 ${DEVICE_FILE}* 158 backup="true" 159 fi 160 161 (( count = count + 1 )) 162 163 case "${vdevs[i]}" in 164 'mirror') (( count == $GROUP_NUM )) && \ 165 action=log_mustnot 166 ;; 167 'raidz') (( count > 1 )) && \ 168 action=log_mustnot 169 ;; 170 'draid') (( count > 1 )) && \ 171 action=log_mustnot 172 ;; 173 '') action=log_mustnot 174 ;; 175 esac 176 177 typeset target=$TESTPOOL1 178 if (( RANDOM % 2 == 0 )) ; then 179 target=$guid 180 log_note "Import by guid." 181 fi 182 $action zpool import \ 183 -d $DEVICE_DIR ${options[j]} $target 184 185 [[ $action == "log_mustnot" ]] && continue 186 187 log_must poolexists $TESTPOOL1 188 189 health=$(zpool list -H -o health $TESTPOOL1) 190 191 [[ $health == "DEGRADED" ]] || \ 192 log_fail "$TESTPOOL1: Incorrect health($health)" 193 log_must ismounted $TESTPOOL1/$TESTFS 194 195 basedir=$TESTDIR1 196 [[ -n ${options[j]} ]] && \ 197 basedir=$ALTER_ROOT/$TESTDIR1 198 199 [[ ! -e $basedir/$TESTFILE0 ]] && \ 200 log_fail "$basedir/$TESTFILE0 missing after import." 201 202 read -r checksum2 _ < <(cksum $basedir/$TESTFILE0) 203 log_must [ "$checksum1" = "$checksum2" ] 204 done 205 206 ((j = j + 1)) 207 done 208 209 recreate_files 210 211 ((i = i + 1)) 212done 213 214log_pass "Import could handle damaged or missing device." 215
