Date: Sun, 14 Aug 2005 14:40:12 -0700 Message-ID: <42FFBA3C.1010102@csun.edu> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1; format=flowed Content-Transfer-Encoding: 7bit Return-path: Sender: linux-raid-owner@vger.kernel.org To: linux-raid@vger.kernel.org List-Id: linux-raid.ids Hi, It seems like this should be a FAQ but careful google and mailing list archive searches didn't seem to turn up anything. I have two machines with legacy RAID-0 arrays created with raidtools. I have updated one to Fedora Core 4 and now use mdadm. Am I correct in thinking I have to use "mdadm --build" every boot to access the array? My mdadm.conf contains DEVICES /dev/hda1 /dev/hdb1 /dev/hdc1 ARRAY /dev/md0 level=raid0 num-devices=3 devices=/dev/hda1,/dev/hdb1,/dev/hdc1 but the array doesn't seem to come up by itself on boot. On the same lines, can this array be converted to a new style array just by writing new superblocks, or do I have to do the backup-reformat-restore thing? TIA.
