Message-ID: <20030612092458.GA29060@merlin.emma.line.org> Mail-Followup-To: Linux-Kernel mailing list Mime-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.4i Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Hi, I haven't followed the status of write barrier patches recently, I am wondering if it's still "necessary" (to avoid file system corruption) to disable the write cache of a SCSI disk drive when the machine doesn't have an uninterruptible power supply or if instead the file systems and driver know how to use ordered tags. (Fujitsu MAP drive: 8 MB cache, AIC7880 adapter, SuSE Linux 8.2 patched 2.4.20 kernel with ext3 and xfs) TIA, -- Matthias Andree
