InnoDB: The OS said file flush did not succeed

This means that you instructed the operating system to write changes to the disk, but they replied that the write failed.Could I say that I failed to save it?

This could be due to insufficient free space on the file system, or to some fault with the file system or disk.

MySQL may have some more information following the error, but if you don't have one, check the OS error log (dmesg or /var/log/messages for Linux).
