btrfs: errors in kernel log

I'm seeing these lines in the kernel log on bootup:

[   19.617839] btrfs: bdev /dev/dm-8 errs: wr 2048, rd 0, flush 0, corrupt 0, gen 0
[   19.617841] btrfs: bdev /dev/dm-7 errs: wr 1727136, rd 362379, flush 0, corrupt 68836, gen 11553

dm-8 and dm-7 belong to a btrfs-raid1 volume consisting of four drives.

I already suspected some drive failure and started two scrubbing runs, but they did not show a single error.

Any idea what could cause these errors, or why the counter is not reset after scrubbing?

Thanks,
