I can't access the web portail anymore

[plush echo]

Hi ! After making some manipulation with the led's connected on the neopixel port of my skr mini e3 v2, I cannot connect to the web portail anymore. I have tried the ip adress, without https, with https and with http. I have tried rebooting the printer, I have tried unplugging the skr mini e3 v2 of the raspberry pi.
In all scenario, I can connect to the ssh via putty, and to the files via filezila, but the web portail is not available. It returns me an issue like if I had no connection or if the website didn't exist ( and the ip adress is correct as i can connect via ssh and filezila)
Any idea what is going on ?
I could give the moonraker, but I doubt it would help, as the last log inside of it is 1-2hours before the issues occured.

I have tried the solution in the other post: https://github.com/mainsail-crew/sonar but, it just tells me : Read-only file system

[shut crystal]

sry.. but how many tags do will add to this post?

pls post screenshots of the error messages. and if you can connect via ssh, you cannot have a wifi issue (like sonar should fix). but the error message with read-only would be interesting.

[shut crystal]

looks like a damaged filesystem

[plush echo]

Is there a fix for this? Or should i do a fresh reinstall?

[shut crystal]

pls post the output of df

[shut crystal]

could be possible, that your disk is just full

[plush echo]

apparently i cannot delete my gcodes

[shut crystal]

because your system started as read only

so fastest way would be to backup your config files and reflash it...

[plush echo]

so the file /home/pi/klipper_config should be enough ?

[shut crystal]

i would also backup the moonraker database

[plush echo]

will do, but may I ask why?

the historic of the printer is there?

[shut crystal]

yes

print history

and all mainsail settings

[plush echo]

is it .moonraker_database?

[shut crystal]

yes

you have to stop moonraker, before you upload this again

(on the new system)

[plush echo]

And how do I do this ? via a ssh command?

[shut crystal]

yes

[plush echo]

okay, we shall see this later then haha, Any other file I should keep?

[shut crystal]

you can backup your gcode files, if you need someone...

[plush echo]

yes, good idea, and I can still keep them in a folder in my pc instead of putting them all inside my printer next time

Another onne? Or am I ready to go?

[shut crystal]

i dont know your system and what you add to it...

[plush echo]

nothing fancy, I think

Alright, Ill go like this ! thanks

ill tell you if it worked

[silver parrot]

Wait a second...

Please post output of cat /etc/fstab

[plush echo]

Sorry... I started reflashing mainsailOS

I'm at 63%. What did you have in mind ?

[silver parrot]

You set to overlay mode by accident

raspi-config nonint disable_overlayfs might have solved it

[plush echo]

well, it finally work now hahaaha, how do i turn off moonraker to add the previous files?

[silver parrot]

Which exactly do you mean?

[plush echo]

i need to import the moonraker database

for this #1044702025721577492 message

[silver parrot]

Oh, I think @shut crystal knows this by far better than me, I am the guy for the layer under this xD

[shut crystal]

sudo systemctl stop moonraker

[silver parrot]

Oops, I misread your question, soory mete 😬

[shut crystal]

np

[plush echo]

and i change stop by start to restart the server?

[shut crystal]

yep

[plush echo]

Thanks !

I think i'm almost there

i am stuck here

now this

[shut crystal]

you have to install or deactivate your rpi mcu

[plush echo]

How do i do that?

[shut crystal]

the same way you did it the last time 🙈

https://www.klipper3d.org/RPi_microcontroller.html

[plush echo]

NICE

it seems to work !

now let's get the led and see if it works

[shut crystal]

pls close this post, when your issue is fixed

[plush echo]

well, the new led doesn't work, but everything does

thanks!

[plush echo]

Okay, first, I'm sorry. I see now that I totally forgot to close this.
I will jump on the occasion: I have an issue with klipper, we've tried a lot of things over on the discord server of klipper, and nothing worked, so I'll try to reinstall it one more time.
I have backed up everything you mentionned here (klipper_config aswell as the moonraker database). I also backed up printer_data and gcode_files. If I want to keep my configuration for my external devices, like the klipper expander, is there something else I should back up ?

[silver parrot]

This tells me you probably used raspi-config to set as an read-only fs ....

[silver parrot]

Not that I am aware of, but please keep in mind not to copy the moonraker.conf blindly over!

Compare the new one with yours, might be possible things changed since then

[plush echo]

Hmm this issue came out of nowhere. It was indeed in read only but IDK why. A file probably got corrupted by the power off without shutting down klipper

[plush echo]

Ill keep this in mind, thanks !
