From mboxrd@z Thu Jan 1 00:00:00 1970 From: Maurice Hilarius Subject: Questions about: Where to find algorithms for RAID5 / RAID6 Date: Tue, 11 Apr 2006 02:50:59 -0600 Message-ID: <443B6DF3.2060500@harddata.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid List-Id: linux-raid.ids Good day. I am looking for some information, and hope the readers of this list might be able to point me in the right direction: Here is the scenario: In RAID5 ( or RAID6) when a file is written, some parity data is created, (by some form of XOR process, I assume), then that parity data is written to disk. I am looking to find the algorithm that is used to create that parity data and to decides where to place it on the disks. Any help on this is deeply appreciated. -- With our best regards, Maurice W.
