ok i see now, i can recover my important files!!!

[1efaf7d71a8637c6800a]

I am happy to hear you could rescue your files.

[Santino]

Thank you, I was no longer able to send you the outputs of the commands you mentioned, as I had a bit of an urgency to continue working, I recovered my files and reinstalled Manjaro, could you recommend me some content to read and understand a little more?

[1efaf7d71a8637c6800a]

I recently had similar issues, thankfully I got helped. I also recovered files from the image so I could help you. Afterwards I was able to fix my btrfs on an m2 ssd.

Repaired btrfs system m2 disk, but there is something wrong with the subvolumes or the system itself

After several system hangs within a few days (I’m on stable and I haven’t updated the 2023-07-10), I can’t boot my system anymore. It hangs on the three-dots bootscreen, “manjaro” below. I tried booting from older LTS kernels which had been installed before I tried booting from snapshots. While listing those in the standard Manjaro boot menu, browsing the snapshots, i.e. moving the cursor up and down everything is lagging. When managing to select a snapshot, trying to boot it gives me either a…

Maybe learn the difference between the /dev and (on Manjaro) /run/media (< mounted drives) folders.

Maybe check out these widgets : Advanced Radio Player - KDE Store
Simple System Monitor - KDE Store

And here on btrfs: Introduction — BTRFS documentation it has all the manuals for the command line progs.
But I would always seek help on the chat https://web.libera.chat/ #btrfs before messing with problems.

Your system must have hit an error booting and when into “protect the system” mode. Try booting into rescue mode and open to a command line. At the command line type:

sudo mount -o remount,rw /

You may need to add your drive to the command.

Good luck.

excellent!!, thanks a lot for share
