FULL(4)                   (2019-03-06)                    FULL(4)

     NAME
          full - always full device

     CONFIGURATION
          If your system does not have /dev/full created already, it
          can be created with the following commands:

              mknod -m 666 /dev/full c 1 7
              chown root:root /dev/full

     DESCRIPTION
          The file /dev/full has major device number 1 and minor
          device number 7.

          Writes to the /dev/full device fail with an ENOSPC error.
          This can be used to test how a program handles disk-full
          errors.

          Reads from the /dev/full device will return \0 characters.

          Seeks on /dev/full will always succeed.

     FILES
          /dev/full
