I will try to get new power supply to test as the current one have
about almost 10 years, so probably it this one the source of the problem.

yes, i have updated backups and i can mount the filesystem without any
problem. I can always reformat the partition and restore, but i would
like to use this to learn how to repair btrfs partitions and help
improving the btrfs if possible.

Check! i'm using btrfs-progs v4.15.1,

done! i was expecting a image with at least my used space ( ~40GB),
but i got a 1GB file. Is that normal?

After booting with a livecd and running a --repair with
btrfs-progs v4.15.1, it didn't look it have done almost anything to the
errors, running a new check still show mostly the same errors:

So looks like btrfs check --repair do not really know how to fix this
Thanks for the help

Naturally the common people don't want war... but after all it is the
leaders of a country who determine the policy, and it is always a
simple matter to drag the people along, whether it is a democracy, or
a fascist dictatorship, or a parliament, or a communist dictatorship.
Voice or no voice, the people can always be brought to the bidding of
the leaders. That is easy. All you have to do is tell them they are
being attacked, and denounce the pacifists for lack of patriotism and
exposing the country to danger. It works the same in every country.
