Problems with your Raspberry Pi are not an issue with the AllSky software, but we're providing this page as a service to Allsky users.

## My Pi isn't using all its disk space

If you have a large SD card like 64 GB but the WebUI's System page shows significantly less, you need to resize the card. For example you see this: but your SD card is much bigger than 28 GB, you need to resize your filesystem:

    sudo resize2fs /dev/sda2

It may ask you to run an `fsck` command then run the resize again. If so, follow its instructions - you'll need to use `sudo`. After the resize, you should have all your space reporting correctly.

## Pi keeps rebooting after a few minutes

One user reported his Pi was stuck in a loop where it would continually reboot after a few minutes. He had removed power from his Pi while it was still running. He fixed the problem by shutting the system down as soon as it came up.

> If you need to shut down your Pi do not simply unplug the power; instead, use the button on the WebUI's System page or via the command prompt:

>     sudo shutdown -r now

## Lenses

Lenses need to be matched to your camera and your environment. If you're in an urban canyon, maybe you don't need a 180° lens. If you have light interference near the horizon you can create an artificial horizon, with a piece of black PVC pipe for example. If you're unsure of the field of view you can use a tool like Bintel to calculate the field of view on the sensor, or Stellarium to simulate the field of view.

## Moisture on dome

If you are getting moisture on the inside of your allsky dome, consider adding a heater. Click here and here.

You can also add a fan to the enclosure that sends air warmed by the Pi into the dome via one hole, and out via another.
