Uses 'sum -r'. 38# 39# STRATEGY: 40# 1. Create a file in the zfs file system 41# 2. Checksum the file for later comparison 42# 3. Create a snapshot of the dataset 43# 4. Append to the original file 44# 5. Verify the snapshot and file agree 45# 46# TESTABILITY: explicit 47# 48# TEST_AUTOMATION_LEVEL: automated 49# 50# CODING_STATUS: COMPLETED (2005-07-04) 51# 52# __stc_assertion_end 53# 54############################################################################### 55 56verify_runnable "both" 57 58function cleanup 59{ 60 snapexists $SNAPFS 61 if [[ $? -eq 0 ]]; then 62 log_must $ZFS destroy $SNAPFS 63 fi 64 65 if [[ -e $SNAPDIR ]]; then 66 log_must $RM -rf $SNAPDIR > /dev/null 2>&1 67 fi 68 69 if [[ -e $TESTDIR ]]; then 70 log_must $RM -rf $TESTDIR/* > /dev/null 2>&1 71 fi 72} 73 74log_assert "Verify a file system snapshot is identical to original." 75 76log_onexit cleanup 77 78log_note "Create a file in the zfs filesystem..." 79log_must $FILE_WRITE -o create -f $TESTDIR/$TESTFILE -b $BLOCKSZ \ 80 -c $NUM_WRITES -d $DATA 81 82log_note "Sum the file, save for later comparison..." 83FILE_SUM=`$SUM -r $TESTDIR/$TESTFILE | $AWK '{ print $1 }'` 84log_note "FILE_SUM = $FILE_SUM" 85 86log_note "Create a snapshot and mount it..." 87log_must $ZFS snapshot $SNAPFS 88 89log_note "Append to the original file..." 90log_must $FILE_WRITE -o append -f $TESTDIR/$TESTFILE -b $BLOCKSZ \ 91 -c $NUM_WRITES -d $DATA 92 93SNAP_FILE_SUM=`$SUM -r $SNAPDIR/$TESTFILE | $AWK '{ print $1 }'` 94if [[ $SNAP_FILE_SUM -ne $FILE_SUM ]]; then 95 log_fail "Sums do not match, aborting!!
