Date: Tue, 4 Aug 2009 14:44:52 -0600 Message-ID: <200908041444.52747.tfjellstrom@shaw.ca> Reply-To: tfjellstrom@shaw.ca Mime-Version: 1.0 Content-Type: Text/Plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org List-Id: linux-raid.ids I'm testing out accessing a "Windows DynamicDisk Raid0" array under linux, and for the most part it works very well. My only problem is mdadm will not auto start the array even when I have it setup in mdadm.conf (mdadm is told to auto start all arrays found there). Basically I have to manually run "mdadm --build /dev/md0 --chunk=64 --level=raid0 --raid-devices=4 /dev/sdc1 /dev/sdd1 /dev/sde1 /dev/sdf1" then "mount /mnt/winraid" when I want to access the filesystem (using ntfs-3g if anyone was wondering). All I get from mdadm/syslog is this: Aug 4 02:43:10 natasha kernel: [ 7.862373] md: md0 stopped. Aug 4 02:43:18 natasha mdadm[3597]: DeviceDisappeared event detected on md device /dev/md0 The reason I'm trying to use non persistent superblocks is I'm assuming trying to save them will damage the windows DynamicDisk metadata in some way. -- Thomas Fjellstrom tfjellstrom@shaw.ca
