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