The file in the origin ds is written without compression or sha256. 28# 2. The file in the origin ds is written before sha256 checksum is turned on. 29# 3. The clone does not have compression. 30# 4. The clone does not have the appropriate checksum. 31# 32 33verify_runnable "global" 34origin="$TESTPOOL/$TESTFS" 35log_onexit cleanup 36 37function cleanup 38{ 39 datasetexists $origin && log_must zfs destroy -R $origin 40 log_must zfs create -o mountpoint=$TESTDIR $origin 41} 42 43log_assert "nopwrite isn't enabled without the prerequisites" 44 45# Data written into origin fs without compression or sha256 46dd if=/dev/urandom of=$TESTDIR/file bs=1024k count=$MEGS conv=notrunc \ 47 >/dev/null 2>&1 || log_fail "dd of $TESTDIR/file failed." 48zfs snapshot $origin@a || log_fail "zfs snap failed" 49log_must zfs clone -o compress=on $origin@a $origin/clone 50log_must zfs set checksum=sha256 $origin/clone 51dd if=/$TESTDIR/file of=/$TESTDIR/clone/file bs=1024k count=$MEGS \ 52 conv=notrunc >/dev/null 2>&1 || log_fail "dd failed." 53log_mustnot verify_nopwrite $origin $origin@a $origin/clone 54zfs destroy -R $origin@a || log_fail "zfs destroy failed" 55log_must rm -f $TESTDIR/file 56 57# Data written to origin fs before checksum enabled 58log_must zfs set compress=on $origin 59dd if=/dev/urandom of=$TESTDIR/file bs=1024k count=$MEGS conv=notrunc \ 60 >/dev/null 2>&1 || log_fail "dd into $TESTDIR/file failed." 61log_must zfs set checksum=sha256 $origin 62zfs snapshot $origin@a || log_fail "zfs snap failed" 63log_must zfs clone $origin@a $origin/clone 64dd if=/$TESTDIR/file of=/$TESTDIR/clone/file bs=1024k count=$MEGS \ 65 conv=notrunc >/dev/null 2>&1 || log_fail "dd failed." 66log_mustnot verify_nopwrite $origin $origin@a $origin/clone 67zfs destroy -R $origin@a || log_fail "zfs destroy failed" 68log_must rm -f $TESTDIR/file 69 70# Clone with compression=off 71dd if=/dev/urandom of=$TESTDIR/file bs=1024k count=$MEGS conv=notrunc \ 72 >/dev/null 2>&1 || log_fail "dd into $TESTDIR/file failed." 73zfs snapshot $origin@a || log_fail "zfs snap failed" 74log_must zfs clone -o compress=off $origin@a $origin/clone 75dd if=/$TESTDIR/file of=/$TESTDIR/clone/file bs=1024k count=$MEGS \ 76 conv=notrunc >/dev/null 2>&1 || log_fail "dd failed." 77log_mustnot verify_nopwrite $origin $origin@a $origin/clone 78zfs destroy -R $origin@a || log_fail "zfs destroy failed" 79log_must rm -f $TESTDIR/file 80 81# Clone with fletcher4, rather than sha256 82dd if=/dev/urandom of=$TESTDIR/file bs=1024k count=$MEGS conv=notrunc \ 83 >/dev/null 2>&1 || log_fail "dd into $TESTDIR/file failed." 84zfs snapshot $origin@a || log_fail "zfs snap failed" 85log_must zfs clone -o checksum=fletcher4 $origin@a $origin/clone 86dd if=/$TESTDIR/file of=/$TESTDIR/clone/file bs=1024k count=$MEGS \ 87 conv=notrunc >/dev/null 2>&1 || log_fail "dd failed." 88log_mustnot verify_nopwrite $origin $origin@a $origin/clone 89 90log_pass "nopwrite isn't enabled without the prerequisites" 91
