I have been having an issue where my log fills up with BTRFS error codes. It starts every night at midnight and then fills the log at around 7.30 in the morning causing execution errors for my docker container.

 

I have tried my best at finding a solution by myself but i can't seem to fix it.

 

Things i've tried:

Disable docker and delete the image.

Increased the log partition but it fills up eventually anyways.

 

The only thing that helps to get rid of the execution errors is a reboot of the server.

There's filesystem corruption on the cache pool, best bet is to backup any important data there and re-format the pool.

Okay. Do you know why it starts every night at midnight?

I read in this thread that loop2 refers to the docker image. It made me think that there could be an error with just the docker image.

Problem first starts with the cache filesystem, then the docker because it's on cache.

Possibly there's something using the cache at that time, like the mover.
