Vicent, Although it can seen naive, I can bet this problem is happening at your brick's posix. From what I understand, GlusterFS has no control over writing or not writing atime. Can you do a "mount|grep noatime" at your servers? If you do this test directly at the storage/posix brick, what happens?
