Manpages - full.4

full - always full device

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

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.

/dev/full

*mknod*(1), *null*(4), *zero*(4)
