Message-Id: <20030419180421.0f59e75b.skraw@ithnet.com> Organization: ith Kommunikationstechnik GmbH X-Mailer: Sylpheed version 0.8.11 (GTK+ 1.2.10; i686-pc-linux-gnu) Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hello all, after shooting down one of this bloody cute new very-big-and-poor IDE drives today I wonder whether it would be a good idea to give the linux-fs (namely my preferred reiser and ext2 :-) some fault-tolerance. I remember there have been some discussions along this issue some time ago and I guess remembering that it was decided against because it should be the drivers issue to give the fs a clean space to live, right? Unfortunately todays' reality seems to have gotten a lot worse comparing to one year ago. I cannot remember a lot of failed drives back then, but today about 20% seemed to be already shipped DOA. Most I came across have only small problems (few dead sectors), but they seemed to produce quite a lot of trouble - at least on my 3ware in non-RAID setup the box partly dies away because reiser feels quite unhappy about the non-recoverable disk-errors. I know this question can get religious, but to name my only point: wouldn't it be a good defensive programming style _not_ to rely on proven-to-be-unreliable hardware manufacturers. Thing is: you cannot prevent buying bad hardware these days, because just about every manufacturer already sold bad apples ... Regards, Stephan
