What is linux sw?

What does the option sw in /etc/fstab under Linux mean?

Problem description:

UUID=ac27f491 in the /etc/fstab file -8dae-43b2-80ed-f17f4cdefaednone swap sw 0 0What does sw mean here?

Answer:

This option is an option in mount. Looking at fstab alone cannot explain the problem.

First take a screenshot of man mount:

1) The mount options here:

       -s     Tolerate sloppy mount options rather than failing. This will ignore mount options not supported by a filesystem type. Not all filesystems
              support this option. This option exists for support of the Linux autofs-based automounter.

means that the wrong options can be ignored, this Options are designed for automatic mounting.

     -w, --rw
              Mount the filesystem read/write. This is the default. A synonym（同义词） is -o rw.

sw should be: automatically mounted read-write partition

2) Your fstab is missing a mount point.
