Message-ID: <20110309090622.GA3570@localhost> MIME-Version: 1.0 Content-Type: text/plain; charset=us-ascii Content-Disposition: inline User-Agent: Mutt/1.5.20 (2009-06-14) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi Greg and Neil, I updated from 2.6.37.2 to 2.6.37.3 yesterday only to find that my raid-0 partitions are no longer recognised. The raid-1 ones still are, though. They did not show up after a reboot. (It has happened once fairly recently that these exact partitions were not recognised but a reboot fixed it -- blamed my disks.) Today I mistakenly booted into 2.6.37.3 again -- still missing. No problems with 2.6.37.2. Browsing the changelog I found f663ed60892c3e1d4490b079a45d9e546271c40c (md: Fix - again - partition detection when array becomes active) and other md-related changes so I figure one of these could perhaps be to blame? As it is my personal/production machine I feel uncomfortable bisecting this at this point, but maybe Neil has an idea of what might be going on? Thanks, Johan
