Comment 3 for bug 1692844

Then ,I change a new way to create a raw device.I add a new disk to my virtual machine and reboot my vm.
Then I get a new clear disk: sdb.
I bind it to the raw device.
raw /dev/raw/raw1 /dev/sdb
chown mysql:mysql /dev/raw/raw1
chmod 660 /dev/raw/raw1

vim /etc/my.cnf
  innodb_data_file_path=/dev/raw/raw1:2Gnewraw

#start the bootstrap node
 service mysql@bootstrap start

I got these errors:
[ERROR] InnoDB: The size of tablespace file /dev/raw/raw1 is only 0, should be at least 65536!

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

As this is a crash and something is definitely wrong, the information
