FULL(4) Linux Programmer's Manual FULL(4)NAMEfull - always full device
If your system does not have /dev/full created already, it can be cre‐
ated with the following commands:
mknod -m 666 /dev/full c 1 7
chown root:root /dev/full
File /dev/full has major device number 1 and minor device number 7.
Writes to the /dev/full device will 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.
