Since testing a large root mountable RAID array is difficult because of the re-boot problem, I re-partitioned my swap space to include a smaller RAID partition for testing purposes. You may find this helpful.

The hdx3 partitions were switched to 'swap' after developing this utility. I could have done it on another machine, however, the libraries and kernels are all about a year or more out of date on my other linux boxes and I preferred to build it on the target machine.
I chose to partition this way and use lodlin rather than lilo because
"/sbin/mkraid /etc/raid1.conf -f --only-superblock"to rebuild the remaining superblock.
cat /proc/mdstat | grep md0 > /dosa/linux/raidgood.ref shutdown -r nowto do a clean reboot, and the system is up again.
