I just noticed my log flowing over with the following errors, litteraly thousends of lines:

I have run a btrfs scrub on the cache drives but there are no errors there.. Also I do not notice any things going wrong on the system..

It is mentioned on the internet in combination with the exact linux distro now part of the latest RC ..

Probably a false warning related to kernel 4.12, supposed to be fixed in 4.13

My syslog is overflowing with the same btrfs error since upgrading to rc7a also. Very much looking forward to the fix.

I have a 2-120GB SSD in a RAID0 BTRFS. I was getting the same warnings. A scrub showed nothing. I ran a balance. When done, I stopped and started the array. The warnings are gone now. Rebooted. Still no warnings.

 

Edit: never mind they came back
