Pi 4 storage used up in weeks?

[evroom]

@dazza120

I would suspect either /tmp being filled up or some log directory being filled up.
Or a log file going AWOL.

You can try to find out which directory under / is using the most:

$ sudo find / -xdev -maxdepth 1 -type d -exec du -s {} \; | sort -rn

When it is working again (perhaps after a reboot you have enough space again), you can look periodically which files are touched / created in the last 60 minutes:

$ sudo find / -xdev -mmin -60 -type f -exec ls -als  {} \;

@evroom hi the first pi code just comes up no access and the other code comes up with a lot of other code thats above my pay grade lol, you could be right but its writting something like a Gb every two hours.

Hi,
I have no idea what you mean with “first pi code” and “the other code”.
2 Pi’s with 2 Magic Mirror instances running?

Do you have ssh access to your Pi 4?
If / is 100% full it normally does not allow you to.
You need to have access again and disable all your modules.
Then check if the / usage is increasing.
If not, or in normal quantity, then allow the modules again one by one, checking the usage after every step.

A reboot might grant you access again, or you might need to take the card out and use a card reader to have access via your PC.
Cleanup /tmp and try to boot from it with your Pi again.

Free space :

sudo df -h /

Usage:

sudo du -sh /
sudo du -sh /tmp 
sudo du -sh /home/pi

Until you have access, trouble shooting is not possible.

Good luck.

I have disabled the NAAO3 module and enabled the default Weather is working fine, stable 25Gb left of space on the SD card. log file is now just 3bytes so hundred percent MMM-NAAO3 is causing the excessive storage useage.

Hi,

I found this to keep the pm2 log under control, pm2-logrotate:

http://pm2.keymetrics.io/docs/usage/log-management/#pm2-logrotate-module

Of course the module needs to be fixed, but this could prevent you from getting a full log again.

I do not have it in use myself.

[dazza120]

@evroom thanks but I’ll wait for a fix, everything is running great at the mo so the mirror is nearly ready to go back on the wall I don’t really want to be taking it down again so I’ll wait for a hard fix. But thanks a lot for your help

[cowboysdude]

@dazza120 It is a provider file issue… and that is the air pollution part of it. If you installed a newer version of MM you may have to run npm install in the NOAA3 dir again…

I am going to try and run it on the Dev machine right now…

I found the issue…go to AirVisual and get a new key… it told me mine was expired…so get a new key and try it again :)

[dazza120]

@cowboysdude hi the key was still active it had 135days to go, I never even clocked that it had an expiration date. Don’t know why they just can’t give a permanent key I don’t want to be changing it every year 😢 got enough tech to keep on top off lol
