Verify make directories only successfully in $(get_snapdir_name). 42# 2. Verify snapshot can be created and destroy via mkdir and remove 43# directories in $(get_snapdir_name). 44# 3. Verify rollback to previous snapshot can succeed. 45# 4. Verify remove directory in snapdir can destroy snapshot. 46# 47# TESTABILITY: explicit 48# 49# TEST_AUTOMATION_LEVEL: automated 50# 51# CODING_STATUS: COMPLETED (2006-10-17) 52# 53# __stc_assertion_end 54# 55################################################################################ 56 57verify_runnable "both" 58 59function cleanup 60{ 61 typeset -i i=0 62 while ((i < snap_cnt)); do 63 typeset snap=$fs@snap.$i 64 datasetexists $snap && log_must $ZFS destroy -f $snap 65 66 ((i += 1)) 67 done 68} 69 70$ZFS 2>&1 | $GREP "allow" > /dev/null 71(($? != 0)) && log_unsupported 72 73log_assert "Verify snapshot can be created via mkdir in $(get_snapdir_name)." 74log_onexit cleanup 75 76[[ $os_name == "FreeBSD" ]] && \ 77 log_uninitiated "Directory operations on the $(get_snapdir_name) directory are not yet supported in FreeBSD" 78 79fs=$TESTPOOL/$TESTFS 80# Verify all the other directories are readonly. 81mntpnt=$(get_prop mountpoint $fs) 82snapdir=$mntpnt/.zfs 83set -A ro_dirs "$snapdir" "$snapdir/snap" "$snapdir/snapshot" 84for dir in ${ro_dirs[@]}; do 85 if [[ -d $dir ]]; then 86 log_mustnot $RM -rf $dir 87 log_mustnot $TOUCH $dir/testfile 88 else 89 log_mustnot $MKDIR $dir 90 fi 91done 92 93# Verify snapshot can be created via mkdir in $(get_snapdir_name) 94typeset -i snap_cnt=5 95typeset -i cnt=0 96while ((cnt < snap_cnt)); do 97 testfile=$mntpnt/testfile.$cnt 98 log_must $MKFILE 1M $testfile 99 log_must $MKDIR $mntpnt/$(get_snapdir_name)/snap.$cnt 100 if ! datasetexists $fs@snap.$cnt ; then 101 log_fail "ERROR: $fs@snap.$cnt should exists." 102 fi 103 104 ((cnt += 1)) 105done 106 107# Verify rollback to previous snapshot succeed. 108((cnt = RANDOM % snap_cnt)) 109log_must $ZFS rollback -r $fs@snap.$cnt 110 111typeset -i i=0 112while ((i < snap_cnt)); do 113 testfile=$mntpnt/testfile.$i 114 if ((i <= cnt)); then 115 if [[ ! -f $testfile ]]; then 116 log_fail "ERROR: $testfile should exists." 117 fi 118 else 119 if [[ -f $testfile ]]; then 120 log_fail "ERROR: $testfile should not exists." 121 fi 122 fi 123 124 ((i += 1)) 125done 126 127# Verify remove directory in snapdir can destroy snapshot. 128log_must $RMDIR $mntpnt/$(get_snapdir_name)/snap.$cnt 129log_mustnot datasetexists $fs@snap.$cnt 130 131log_pass "Verify snapshot can be created via mkdir in $(get_snapdir_name) passed." 132
