No free space on SD-card


  • Hi all
    I’ve no de why, but I’ve no space on SD-Card. It’s 8GB and there is just Rapsian+MM+ some modules+VNC. Could be the problem any module, that it stores locally a lot of data? I’ve:
    Calendar
    Current Weather
    Complimetns
    MMM-AirQuality by CFenner
    calendar_monthly by KirAsh4
    MMM-Netatmo by CFenner
    MMM-NetworkScanner by ianperrin
    MMM-WunderGround by RedNax67

    And now, after restart Raspberry do not start at all 😞

    So, how to check the data? how to find the biggest files? How to delete them? I can put SD into Mac or Win machine…

    and what to do to not happen in future again?

    thanks, Zdenek

    @zdenek sounds more like a defective sd-card if the Pi won’t start at all.

  • @broberg ok, it starts, there is planty of rows with green OK on the left, than monitor goes to clean and it’s just “black” - like GUI doesn’t start

    could check if there is a file named core inside of your MagicMirror folder. Snille had an issue which created this huge file:

  • @yawns nope 😞 actually, there is about 40 MB and it starts. So, Raspberry is running. I huess 8GB should be enough. Or not? How to find biggets file and delete?

    try to run this on console:
    find -type f -exec du -Sh {} + | sort -rh | head -n 5

    This should bring up the 5 biggest files

    thanks, but it didn’t find any abnormal larg file

    43M	./MagicMirror/node_modules/electron/dist/electron
37M	./.electron/electron-v1.4.15-linux-arm.zip
15M	./MagicMirror/node_modules/electron/dist/libnode.so
14M	./MagicMirror/node_modules/clarinet/test/twitter.js
14M	./MagicMirror/node_modules/clarinet/samples/twitter.json

    so, could be there a milions of small (let say 1MB) files/logs? I’ve no problem to buy bigger SD, but if there asi any problem with growing files, even 1TB SD card will be one day full…

    Are you really sure your sd card is full?
    Please run df -h to check for disk space (maybe you need to run sudo df -h, not sure)

    I guess the last 2GB is recovery or smthg like that
