MDEV service stopped

lferrara

Today the mdev service stopped. No changes or reboot was done.
Strange!

What's wrong?

    Lanching the command: service mdev:start -dsnosync putted the service into unregistered status and now services icon is green again.

    However, having a list of what each service does, would help us to investigate and troubleshoot XG more easily.

    Sophos you should create a KB with the meaning of each service (most of them are already known but others.....)

    Thanks

    Hi Luk,

    As far as I know, mdev is a light-weight alternative to udev. This handles the creation of device files in /dev directory and starting of actions when certain events happen. For example- when I connect a USB dongle to my XG appliance mdev service will handle the creation and starting of the event in backend. Check the logs:

    XG# tail -f mdev.log
