Root RAID HOWTO cookbook Root RAID HOWTO cookbook Michael A. Robinton, [e-mail]1.07, 25 March 1998This document provides a cookbook for creating a root mounted raid filesystem and companion fallback rescue system using linux initrd. There are complete step-by-step instruction for both raid1 and raid5 md0 devices. Each step is accompanied by an explanation of it's purpose. Included with this revision is a generic linuxrc initrd file which may be configured with a single three line /etc/raidboot.conf file for raid1 and raid5 configurations.1.
