Content-Type: text/plain; charset=ISO-8859-1 Sender: linux-btrfs-owner@vger.kernel.org List-ID: Hi there, I've started "btrfs scrub start /" on one of my machines (Kernel 3.8.0-15 Ubuntu AMD64), which typically "behaves well" so I wasn't suspected any disk issue. After having ran for only 165 seconds, "scrub status" shows it pretends having found and corrected 22926 CSUM errors ??!?!?!?!!??? This is a rather new HDD, in perfect shape (SMART all OK, never reallocated a single sector, less than 200 hours total runtime...) WTF ?!? I've cancelled scrub for now, until I get further understanding of what can be happening... -- Swâmi Petaramesh http://petaramesh.org PGP 9076E32E Ne cherchez pas : Je ne suis pas sur Facebook.
