I wanted to create a backup of my OctoPrint configuration. Unfortunately, I forgot to uncheck the option to exclude all my uploaded files. Therefore, the system must have run out of disk space, and backup failed with input/output error. Subsequently, I was unable to ssh into the system: error kex_exchange_identification: read: Connection reset. I am guessing because the system is out of free space. Then I tried to reboot using the UI. This did not work, no response from pressing the reboot button. Then I tried to reboot by power cycling, but my octopi is now refusing to boot up, probably because it is out of disk space.
I do not have a Linux system to mount the SD card to try to delete the failed backup.
What did you already try to solve it?
See above
Have you tried running in safe mode?
Unable to boot octopi
Did running in safe mode solve the problem?
see above
Systeminfo Bundle
You can download this in OctoPrint's System Information dialog ... no bundle, no support!)
Unable to boot - can't check
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
unable to boot - can't find this information
Conclusion: wanted to backup my system configuration, so I could upgrade OctoPrint / octopi with a new image and a Python version that's not end-of-life. OctoPrint's backup feature ended up filling all available free space, rendering octopi unbootable.
Advice? I had really hoped I could backup my system before an upgrade so I would not have to restore all plugins and configuration from scratch.
