[arm-allstar] fsck on PI image

[Doug Crompton]

Bernie,

 There are a number of ways to shutdown the Pi. Already in the code is the ability to shutdown with a GPIO push button. You just have to add the button and activate it in the allstar.env file. A howto is on the web page.

There are also functions in rpt.conf that are commented out that allow dtmf asterisk restart, linux reboot, and system halt. You could uncomment them and possibly change the dtmf codes.

As far a power down problems without shutting down properly I have never seen a problem with the RPi2 image but of course it is always a good idea to shutdown properly. It does not take much to run the RPI2 for hours of power failure. A 400 watt UPS would run it all day.

The image is ext4 and does the same things it would do on any other OS.

I don't think it is anything you have to really worry about as long as you take a few precautions and of course always have an image backup on hand. They are easy to make with the backup scripts.
