One with compression 38# and one without. Ensure the compressed file is smaller. 39# 40# NOTE: This test uses a dataset rather than a simple file system. 41# 42# STRATEGY: 43# Create a dataset, turn on compression and create files before 44# and after the property change. The compressed file should be smaller. 45# 46 47verify_runnable "both" 48 49typeset OP=create 50 51log_assert "Ensure that compressed files in a dataset are smaller." 52 53log_note "Ensure compression is off" 54log_must zfs set compression=off $TESTPOOL/$TESTCTR 55 56log_note "Writing file without compression..." 57log_must file_write -o $OP -f $TESTDIR1/$TESTFILE0 -b $BLOCKSZ \ 58 -c $NUM_WRITES -d $DATA 59 60log_note "Add compression property to the dataset and write another file" 61log_must zfs set compression=on $TESTPOOL/$TESTCTR 62 63log_must file_write -o $OP -f $TESTDIR1/$TESTFILE1 -b $BLOCKSZ \ 64 -c $NUM_WRITES -d $DATA 65 66sleep 60 67 68FILE0_BLKS=`du -k $TESTDIR1/$TESTFILE0 | awk '{ print $1}'` 69FILE1_BLKS=`du -k $TESTDIR1/$TESTFILE1 | awk '{ print $1}'` 70 71if [[ $FILE0_BLKS -le $FILE1_BLKS ]]; then 72 log_fail "$TESTFILE0 is smaller than $TESTFILE1" \ 73 "($FILE0_BLKS <= $FILE1_BLKS)" 74fi 75 76log_pass "$TESTFILE0 is bigger than $TESTFILE1 ($FILE0_BLKS > $FILE1_BLKS)" 77
