Create test pool upon device files using the various combinations. 52# - Regular pool 53# - Mirror 54# - Raidz 55# - dRAID 56# 2. Create necessary filesystem and test files. 57# 3. Export the test pool. 58# 4. Move one or more device files to other directory 59# 5. Verify 'zpool import -d' with the new directory 60# will handle moved files successfully. 61# Using the various combinations. 62# - Regular import 63# - Alternate Root Specified 64# 65 66verify_runnable "global" 67 68# Randomly test a subset of combinations to speed up the test. 69(( rc=RANDOM % 3 )) 70if [[ $rc == 0 ]] ; then 71 set -A vdevs "" "mirror" "raidz" 72elif [[ $rc == 1 ]] ; then 73 set -A vdevs "" "mirror" "draid" 74else 75 set -A vdevs "" "raidz" "draid" 76fi 77 78set -A options "" "-R $ALTER_ROOT" 79 80function cleanup 81{ 82 cd $DEVICE_DIR || log_fail "Unable change directory to $DEVICE_DIR" 83 [[ -e $DEVICE_DIR/$DEVICE_ARCHIVE ]] && \ 84 log_must tar xf $DEVICE_DIR/$DEVICE_ARCHIVE 85 86 poolexists $TESTPOOL1 || \ 87 log_must zpool import -d $DEVICE_DIR $TESTPOOL1 88 89 cleanup_filesystem $TESTPOOL1 $TESTFS 90 91 destroy_pool $TESTPOOL1 92} 93 94function cleanup_all 95{ 96 cleanup 97 98 # recover dev files 99 typeset i=0 100 while (( i < $MAX_NUM )); do 101 typeset dev_file=${DEVICE_DIR}/${DEVICE_FILE}$i 102 if [[ ! -e ${dev_file} ]]; then 103 log_must rm -f ${dev_file} 104 log_must truncate -s $FILE_SIZE ${dev_file} 105 fi 106 ((i += 1)) 107 done 108 109 log_must rm -f $DEVICE_DIR/$DEVICE_ARCHIVE 110 cd $CWD || log_fail "Unable change directory to $CWD" 111 112 [[ -d $ALTER_ROOT ]] && \ 113 log_must rm -rf $ALTER_ROOT 114 115 [[ -d $BACKUP_DEVICE_DIR ]] && \ 116 log_must rm -rf $BACKUP_DEVICE_DIR 117} 118 119log_onexit cleanup_all 120 121log_assert "Verify that import could handle moving device." 122 123CWD=$PWD 124 125[[ ! -d $BACKUP_DEVICE_DIR ]] && 126 log_must mkdir -p $BACKUP_DEVICE_DIR 127 128cd $DEVICE_DIR || log_fail "Unable change directory to $DEVICE_DIR" 129 130typeset -i i=0 131typeset -i j=0 132typeset -i count=0 133typeset basedir backup 134typeset action 135 136while (( i < ${#vdevs[*]} )); do 137 138 (( i != 0 )) && \ 139 log_must tar xf $DEVICE_DIR/$DEVICE_ARCHIVE 140 141 setup_filesystem "$DEVICE_FILES" \ 142 $TESTPOOL1 $TESTFS $TESTDIR1 \ 143 "" ${vdevs[i]} 144 145 guid=$(get_config $TESTPOOL1 pool_guid) 146 backup="" 147 148 log_must cp $MYTESTFILE $TESTDIR1/$TESTFILE0 149 150 log_must zfs umount $TESTDIR1 151 152 j=0 153 while (( j < ${#options[*]} )); do 154 155 count=0 156 157 # 158 # Restore all device files. 159 # 160 [[ -n $backup ]] && \ 161 log_must tar xf $DEVICE_DIR/$DEVICE_ARCHIVE 162 163 log_must rm -f $BACKUP_DEVICE_DIR/* 164 165 for device in $DEVICE_FILES ; do 166 167 poolexists $TESTPOOL1 && \ 168 log_must zpool export $TESTPOOL1 169 170 # 171 # Backup all device files while filesystem prepared. 172 # 173 if [[ -z $backup ]] ; then 174 log_must tar cf $DEVICE_DIR/$DEVICE_ARCHIVE \ 175 ${DEVICE_FILE}0 ${DEVICE_FILE}1 ${DEVICE_FILE}2 176 backup="true" 177 fi 178 179 log_must mv $device $BACKUP_DEVICE_DIR 180 181 (( count = count + 1 )) 182 183 action=log_mustnot 184 case "${vdevs[i]}" in 185 'mirror') (( count < $GROUP_NUM )) && \ 186 action=log_must 187 ;; 188 'raidz') (( count == 1 )) && \ 189 action=log_must 190 ;; 191 'draid') (( count == 1 )) && \ 192 action=log_must 193 ;; 194 esac 195 196 typeset target=$TESTPOOL1 197 if (( RANDOM % 2 == 0 )) ; then 198 target=$guid 199 log_note "Import by guid." 200 fi 201 $action zpool import \ 202 -d $DEVICE_DIR ${options[j]} $target 203 204 done 205 206 ((j = j + 1)) 207 done 208 209 cleanup 210 211 ((i = i + 1)) 212done 213 214log_pass "Import could handle moving device." 215
