Write unique data to a filesystem and create a compressed, deduplicated 26# full stream. 27# 2. Verify that the stream and send dataset show the same size 28# 3. Make several copies of the original data, and create both full and 29# incremental compressed, deduplicated send streams 30# 4. Verify the full stream is no bigger than the stream from step 1 31# 5. Verify the streams can be received correctly. 32# 33 34verify_runnable "both" 35 36log_assert "Verify that the -c and -D flags do not interfere with each other" 37log_onexit cleanup_pool $POOL2 38 39typeset sendfs=$POOL2/sendfs 40typeset recvfs=$POOL2/recvfs 41typeset stream0=$BACKDIR/stream.0 42typeset stream1=$BACKDIR/stream.1 43typeset inc=$BACKDIR/stream.inc 44 45log_must zfs create -o compress=lz4 $sendfs 46log_must zfs create -o compress=lz4 $recvfs 47typeset dir=$(get_prop mountpoint $sendfs) 48# Don't use write_compressible: we want compressible but undedupable data here. 49log_must eval "dd if=/dev/urandom bs=1024k count=4 | base64 >$dir/file" 50log_must zfs snapshot $sendfs@snap0 51log_must eval "zfs send -D -c $sendfs@snap0 >$stream0" 52 53# The stream size should match at this point because the data is all unique 54verify_stream_size $stream0 $sendfs 55 56for i in {0..3}; do 57 log_must cp $dir/file $dir/file.$i 58done 59log_must zfs snapshot $sendfs@snap1 60 61# The stream sizes should match, since the second stream contains no new blocks 62log_must eval "zfs send -D -c $sendfs@snap1 >$stream1" 63typeset size0=$(stat -c %s $stream0) 64typeset size1=$(stat -c %s $stream1) 65within_percent $size0 $size1 90 || log_fail "$size0 and $size1" 66 67# Finally, make sure the receive works correctly. 68log_must eval "zfs send -D -c -i snap0 $sendfs@snap1 >$inc" 69log_must eval "zfs recv -d $recvfs <$stream0" 70log_must eval "zfs recv -d $recvfs <$inc" 71cmp_ds_cont $sendfs $recvfs 72 73# The size of the incremental should be the same as the initial send. 74typeset size2=$(stat -c %s $inc) 75within_percent $size0 $size2 90 || log_fail "$size0 and $size1" 76 77log_pass "The -c and -D flags do not interfere with each other" 78
