Create test pool upon device files using the various combinations. 54# - Regular pool 55# - Mirror 56# - Raidz 57# 2. Create necessary filesystem and test files. 58# 3. Export the test pool. 59# 4. Move one or more device files to other directory 60# 5. Verify 'zpool import -d' with the new directory 61# will handle moved files successfullly. 62# Using the various combinations. 63# - Regular import 64# - Alternate Root Specified 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 81log_onexit cleanup_missing 82 83log_assert "Verify that import could handle moving device." 84 85log_must $MKDIR -p $BACKUP_DEVICE_DIR 86cd $DEVICE_DIR || log_fail "Unable change directory to $DEVICE_DIR" 87 88typeset -i i=0 89typeset -i count=0 90typeset action 91 92function try_import # <action> <poolish> [opts] 93{ 94 typeset action=$1; shift 95 typeset poolish="$1"; shift 96 log_note "try_import action=$action poolish=$poolish opts='$1'" 97 if [ -z "$1" ]; then 98 $action $ZPOOL import -d $DEVICE_DIR $poolish 99 else 100 $action $ZPOOL import -d $DEVICE_DIR $1 $poolish 101 fi 102 [ "$action" = "log_mustnot" ] && return 103 log_must $ZPOOL export $TESTPOOL1 104} 105 106while :; do 107 typeset vdtype="${vdevs[i]}" 108 109 typeset -i j=0 110 while (( j < ${#options[*]} )); do 111 typeset opts="${options[j]}" 112 113 [ -n "$vdtype" ] && typestr="$vdtype" || typestr="stripe" 114 setup_missing_test_pool $vdtype 115 guid=$(get_config $TESTPOOL1 pool_guid $DEVICE_DIR) 116 log_note "*** Testing $typestr tvd guid $guid opts '${opts}'" 117 118 typeset -i count=0 119 for device in $DEVICE_FILES ; do 120 log_mustnot poolexists $TESTPOOL1 121 log_must $MV $device $BACKUP_DEVICE_DIR 122 123 (( count = count + 1 )) 124 125 action=log_mustnot 126 case "${vdevs[i]}" in 127 'mirror') (( count < $GROUP_NUM )) && \ 128 action=log_must 129 ;; 130 'raidz') (( count == 1 )) && \ 131 action=log_must 132 ;; 133 esac 134 135 log_note "Testing import by name; ${count} moved." 136 try_import $action $TESTPOOL1 "$opts" 137 138 log_note "Testing import by GUID; ${count} moved." 139 try_import $action $guid "$opts" 140 done 141 142 log_must $RM -f $BACKUP_DEVICE_DIR/* 143 recreate_missing_files 144 ((j = j + 1)) 145 done 146 ((i = i + 1)) 147 (( i == ${#vdevs[*]} )) && break 148done 149 150log_pass "Import could handle moving device." 151
