For random compression types, and compressible / incompressible data: 28# 2. Create a snap with data 29# 3. Compare the size of the stream with the data on the dataset, adjusted 30# by compressratio for normal send, and compared to used for send -c. 31# 32 33verify_runnable "both" 34 35log_assert "Verify send -c streams are compressed" 36log_onexit cleanup_pool $POOL2 37 38typeset sendfs=$POOL2/$FS 39typeset megs=128 40 41for prop in "${compress_prop_vals[@]}"; do 42 for compressible in 'yes' 'no'; do 43 log_must zfs create -o compress=$prop $sendfs 44 45 if [[ $compressible = 'yes' ]]; then 46 write_compressible $(get_prop mountpoint $sendfs) \ 47 ${megs}m 48 else 49 typeset file="$(get_prop mountpoint $sendfs)/ddfile" 50 log_must dd if=/dev/urandom of=$file bs=1024k count=$megs 51 fi 52 53 log_must zfs snapshot $sendfs@snap 54 55 # Calculate the sizes and verify the compression ratio. 56 log_must eval "zfs send $sendfs@snap >$BACKDIR/uncompressed" 57 verify_stream_size $BACKDIR/uncompressed $sendfs 58 59 log_must eval "zfs send -c $sendfs@snap >$BACKDIR/compressed" 60 verify_stream_size $BACKDIR/compressed $sendfs 61 62 log_must rm $BACKDIR/uncompressed $BACKDIR/compressed 63 log_must_busy zfs destroy -r $sendfs 64 done 65done 66 67log_pass "Verify send -c streams are compressed" 68
