VenusOS Root Filesystem Full, Free up disk space

Hi All,
I searched this question all over but seems like I don’t have anyone with similar question. I have installed some other packages over time, but the root partition is full now. I run the resize command but it just says already completed. I have 60gb available but not being used. Any guidance on how to increase root partition size would be appreciated.

Device is a Cerbo-GX

root@Cerbo:/# df -h

The filesystem is already 327680 (4k) blocks long.  Nothing to do!

Dunno exactly what the possibilities are in Venus linux, but i do know that this is not the right command to grow a partition. growing a root partition is pretty dangerous and done offline, but you can not take the soldered mmc out so that makes growing a root partition in an Cerbo impossible.
you may be able to store logs and packages on the external memory tough.

Maybe you can start by cleaning up some old log files ?

The 60GB is on a external memory card i see?

Many posts in the old community, now archived. Typically happens with large Node Red installs or 3rd party add ins that do not keep log files tidy. I thought that there had been some recent mods to Venus OS to try and keep this under control.

You’re absolutely right—growing a root partition is risky business, especially on a system like the Cerbo with a soldered eMMC. Doing it offline is the only safe way, but without the option to remove the memory, it’s practically a no-go. Shifting logs or packages to the external memory could be a good workaround, though. Cleaning up old log files is definitely a great place to start—those can build up fast and eat space. Curious, is the 60GB external card being fully utilized yet?

The 60gb card looks completely un-utilized right now.
I think I am just going to do factory reset on the cerbo and start over, see if anything is different.

Hi,
I followed the directions here to try to factory reset the Cerbo GX.
18. Reset to factory defaults and Venus OS reinstall

I did the first option, and it seemed to work as a lot of settings were reset but the root disk remained at 99% full.

Then I tried the 2nd option flashing the firmware to a usb drive and booting. I didn’t notice that anything happened as the device booted right up each time, no beeping sounds like the first method. Maybe if I can get it to flash then the space will free up, but so far I’m still completely stuck…

have you had a screen connected to the HDMI port? (even a tv will do)
