Summary: Copy a file with a size of 102400000 bytes and md5sum 4b494e501587eb28925b151a3b4d67e3, with scp, to a gluster folder. Result is that two gluster clients see a wrong md5sum. The checksum in one brick is correct, in the other brick is wrong. File size is the same as seen from the clients and the bricks.
