Auto run when usb is mounted

[Paul5]

Any chance of having an auto run function when a USB is inserted and mounted by FreenNas.

FreeNas already auto mounts USB's I just need it to auto run a script in the USB straight after it's mounted.

In my case. Poor mans UPS shutdown. I have an old UPS that I tried to connect to Freenas via serial trying different drivers. My reward, a fully corrupted Freenas, the screen looked like the Matrix on steroids. Don't ask me how it happened.

All I need to do is have a relay on the old UPS, when power fails and the UPS takes over, the relay completes the circuit which powers the usb. Freenas sees it as newly inserted and mounts it, the script runs telling freenas to shutdown in X seconds.

Others would find and auto run feature of use for something (quick back up of config files?). So it would be nice to have the option.

You can schedule a cron job (http://doc.freenas.org/index.php/Cron_Jobs) to run every minute and check for existence of the specific /dev file.

I thought of that, but would it not just take up resources looking for a file/script that may only show up once a year, if that.

What's the UPS? You may not have had the correct serial cable for it.

That's a good point I might have to see if I can find another one from somewhere.

The UPS - It's an MLA BS-1200 judging by the electronics I would say it's from the 90's
