Boot partition leaking space Topic is solved

[azonneveld]

Recently I discovered that the rpi's bootpartition is losing space slowly.

Yesterday at 1600hrs I ran clean/autoremove/etc, which regained 3% diskspace, but the proces of leaking space continues.
This is not causing any issues yet, but I think it will soon.

Does anyone know how to fix this, or how to find the source?

Kind of hard to say without knowing more about your system. What background tasks are running? What cron jobs? Do you do automatic updates/upgrades? Any tools that are filling up logs? Log rotation not working correctly?

I have influxdb and grafana installed and can monitor both the system as well as domoticz. There are great dashboards readily available to get interesting insights. I would start by identifying when it happens and figuring out what is running when it happens.

One thing you can also do is to define a cron job that logs usage of various folders to a file (in /tmp) every 12 hours or so. That way, you can compare. This can also be pushed to influxDB so you can easily graph it again. Issue "sudo du -xsh /*" which will give you disk usage in human readable form of all subfolders but without travwersing mounted file systems (in case you have those).

system: rpi 3b+

The "/boot" folder is the one which is leaking space.
The boot partition is read-only, set by the RPI GUI.
I have ran the command, these are the results:

Seemed some logging was enabled for some camera pictures.
Thanks for the support!
