No message get logged for my other two traditional HD that are btrfs also. Warnings show only on boot and not on every boot. Kernel is now 4.12.5 but I got that till upgrading to 4.12, in 4.11 no warnings. Just wanted to know if I have to worry about this, scrubs are ok and btrfs check give me no problems. Thank you very much. Mario.
