watchdog service is not working because /dev/watchdog does not exist

Solution Verified - Updated -


When using the software watchdog from the package watchdog, the needed /dev/watchdog is not created automatically.

This results in the following message in /var/log/messages:

watchdog: cannot open /dev/watchdog (errno = 2 = 'No such file or directory')


  • Red Hat Enterprise Linux 5
  • no hardware watchdog built into the server
