Create test pool upon device files using the various combinations. 52# - Regular pool 53# - Mirror 54# - Raidz 55# 2. Create necessary filesystem and test files. 56# 3. Export the test pool. 57# 4. Remove one or more devices 58# 5. Verify 'zpool import' will handle d/m device successfully. 59# Using the various combinations. 60# - Regular import 61# - Alternate Root Specified 62# It should be succeed with single d/m device upon 'raidz' & 'mirror', 63# but failed against 'regular' or more d/m devices. 64# 6. If import succeed, verify following is true: 65# - The pool shows up under 'zpool list'. 66# - The pool's health should be DEGRADED. 67# - It contains the correct test file 68# 69# TESTABILITY: explicit 70# 71# TEST_AUTOMATION_LEVEL: automated 72# 73# CODING_STATUS: COMPLETED (2005-08-01) 74# 75# __stc_assertion_end 76# 77################################################################################ 78 79verify_runnable "global" 80 81set -A vdevs "" "mirror" "raidz" 82set -A options "" "-R $ALTER_ROOT" 83 84function perform_inner_test 85{ 86 typeset action=$1 87 typeset import_opts=$2 88 typeset target=$3 89 typeset basedir 90 91 $action $ZPOOL import -d $DEVICE_DIR ${import_opts} $target 92 [[ $action == "log_mustnot" ]] && return 93 94 log_must poolexists $TESTPOOL1 95 96 health=$($ZPOOL list -H -o health $TESTPOOL1) 97 [[ "$health" == "DEGRADED" ]] || \ 98 log_fail "ERROR: $TESTPOOL1: Incorrect health '$health'" 99 log_must ismounted $TESTPOOL1/$TESTFS 100 101 basedir=$TESTDIR1 102 [[ -n "${import_opts}" ]] && basedir=$ALTER_ROOT/$TESTDIR1 103 [[ ! -e "$basedir/$TESTFILE0" ]] && \ 104 log_fail "ERROR: $basedir/$TESTFILE0 missing after import." 105 106 checksum2=$($SUM $basedir/$TESTFILE0 | $AWK '{print $1}') 107 [[ "$checksum1" != "$checksum2" ]] && \ 108 log_fail "ERROR: Checksums differ ($checksum1 != $checksum2)" 109 110 log_must $ZPOOL export $TESTPOOL1 111} 112 113log_onexit cleanup_missing 114 115log_assert "Verify that import could handle damaged or missing device." 116 117CWD=$PWD 118cd $DEVICE_DIR || log_fail "ERROR: Unable change directory to $DEVICE_DIR" 119 120checksum1=$($SUM $MYTESTFILE | $AWK '{print $1}') 121 122typeset -i i=0 123while :; do 124 typeset vdtype="${vdevs[i]}" 125 126 typeset -i j=0 127 while (( j < ${#options[*]} )); do 128 typeset opts="${options[j]}" 129 [ -n "$vdtype" ] && typestr="$vdtype" || typestr="stripe" 130 131 # Prepare the pool. 132 setup_missing_test_pool $vdtype 133 guid=$(get_config $TESTPOOL1 pool_guid $DEVICE_DIR) 134 log_note "*** Testing $typestr tvd guid $guid opts '${opts}'" 135 136 typeset -i count=0 137 for device in $DEVICE_FILES ; do 138 log_mustnot poolexists $TESTPOOL1 139 log_must $RM -f $device 140 141 (( count = count + 1 )) 142 143 action=log_must 144 case "$vdtype" in 145 'mirror') (( count == $GROUP_NUM )) && \ 146 action=log_mustnot 147 ;; 148 'raidz') (( count > 1 )) && \ 149 action=log_mustnot 150 ;; 151 '') action=log_mustnot 152 ;; 153 esac 154 155 log_note "Testing import by name; ${count} removed." 156 perform_inner_test $action "${opts}" $TESTPOOL1 157 158 log_note "Testing import by GUID; ${count} removed." 159 perform_inner_test $action "${opts}" $guid 160 done 161 162 recreate_missing_files 163 (( j = j + 1 )) 164 done 165 (( i = i + 1 )) 166 (( i == ${#vdevs[*]} )) && break 167done 168 169log_pass "Import could handle damaged or missing device." 170
