comment:        This occured when copying (rsync -rvu) video files from /dev/sdb1 (ext3) to /dev/sdc (btrfs 16K nodes). The btrfs is newly created and mounted. Tested with copying some smaller files (documents total 1.2GB) and they worked fine. System is FC16 default installation. all the HDDs were working drives just pulled off from FC14 software raid 5.
