The original on-disk value will be 38# restored when the file system is unmounted and mounted. 39# 40# PROPERTY MOUNT OPTION 41# atime atime/noatime 42# devices devices/nodevices 43# exec exec/noexec 44# readonly ro/rw 45# setuid setuid/nosetuid 46# 47# STRATEGY: 48# 1. Create filesystem and get original property value. 49# 2. Using 'zfs mount -o' to set filesystem property. 50# 3. Verify the property was set temporarily. 51# 4. Verify it will not affect the property that is stored on disk. 52# 53 54function cleanup 55{ 56 if ! ismounted $TESTPOOL/$TESTFS; then 57 log_must zfs mount $TESTPOOL/$TESTFS 58 fi 59} 60 61log_assert "Verify '-o' will set filesystem property temporarily, " \ 62 "without affecting the property that is stored on disk." 63log_onexit cleanup 64 65set -A properties "atime" "exec" "readonly" "setuid" 66if ! is_freebsd; then 67 properties+=("devices") 68fi 69 70# 71# Get the specified filesystem property reverse mount option. 72# 73# $1 filesystem 74# $2 property 75# 76function get_reverse_option 77{ 78 typeset fs=$1 79 typeset prop=$2 80 81 # Define property value: "reverse if value=on" "reverse if value=off" 82 if is_linux; then 83 set -A values "noatime" "atime" \ 84 "noexec" "exec" \ 85 "rw" "ro" \ 86 "nosuid" "suid" \ 87 "nodev" "dev" 88 elif is_freebsd; then 89 set -A values "noatime" "atime" \ 90 "noexec" "exec" \ 91 "rw" "ro" \ 92 "nosetuid" "setuid" 93 else 94 set -A values "noatime" "atime" \ 95 "noexec" "exec" \ 96 "rw" "ro" \ 97 "nosetuid" "setuid" \ 98 "nodevices" "devices" 99 fi 100 101 typeset -i i=0 102 while (( i < ${#properties[@]} )); do 103 if [[ $prop == ${properties[$i]} ]]; then 104 break 105 fi 106 107 (( i += 1 )) 108 done 109 if (( i >= ${#properties[@]} )); then 110 log_fail "Incorrect option: $prop" 111 fi 112 113 typeset val 114 typeset -i ind=0 115 val=$(get_prop $prop $fs) 116 if [[ $val == "on" ]]; then 117 (( ind = i * 2 )) 118 else 119 (( ind = i * 2 + 1 )) 120 fi 121 122 echo ${values[$ind]} 123} 124 125fs=$TESTPOOL/$TESTFS 126cleanup 127 128for property in ${properties[@]}; do 129 orig_val=$(get_prop $property $fs) 130 131 # Set filesystem property temporarily 132 reverse_opt=$(get_reverse_option $fs $property) 133 log_must zfs unmount $fs 134 log_must zfs mount -o $reverse_opt $fs 135 136 cur_val=$(get_prop $property $fs) 137 138 # In LZ, a user with all zone privileges can never with "devices" 139 if ! is_global_zone && [[ $property == devices ]] ; then 140 if [[ $cur_val != off || $orig_val != off ]]; then 141 log_fail "'devices' property shouldn't " \ 142 "be enabled in LZ" 143 fi 144 elif [[ $orig_val == $cur_val ]]; then 145 log_fail "zfs mount -o $reverse_opt " \ 146 "doesn't change property." 147 fi 148 149 # unmount & mount will revert property to the original value 150 log_must zfs unmount $fs 151 log_must zfs mount $fs 152 153 cur_val=$(get_prop $property $fs) 154 if [[ $orig_val != $cur_val ]]; then 155 log_fail "zfs mount -o $reverse_opt " \ 156 "change the property that is stored on disks" 157 fi 158done 159 160log_pass "Verify '-o' set filesystem property temporarily passed." 161
