Root RAID HOWTO cookbook
v1.13, July 17, 2000
This document only applys to the OLD raidtools, versions 0.50 and
under. The workarounds and solutions addressed in this write up have largely
been made obsolete by the vast improvment in the 0.90 raidtools and
accompanying kernel patch to the 2.0.37, 2.2x and 2.3x series kernels. You
may find the detailed descriptions useful, particularly if you plan to run
root raid or use initrd. Check these links for a reference to set up of
Boot Root Raid using conventional LILO and accompanying initrd working scripts. What
follows is the description of the now OBSOLETE Root RAID HOWTO.
This document was originally written to provide 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.
