Raid1 auto-detection...

Raid1 auto-detection...

[Bob Hillegas]

I am currently using Fedora Core 2 kernel 2.6.8-1.521smp. I have set up
a raid1 on /dev/md0 from /dev/sda1 & /dev/sdb1. Both partitions have
been set to type 0xfd.

When I boot the raid is not started. After the boot has completed I can
manually mdadm --assemble --scan & mdadm --stop --scan, so I know I have
a workable raid1 setup.

Q1) How do I check the kernel to see whether auto-detection is included?

Q2) Can you point me to a good site for compiling in auto-detection?

Thanks, BobH

I know it's bad form to reply to your own message, but I just resolved
my problem.

The Fedora Core 2 kernel isn't the source of the problem. It's the
rc.sysinit script. It expects to use raidstart and so checks for the
presence of the /etc/raidtab file. Since I don't have one, no attempt
was made to start the raid.

I'll hammer together changes to allow mdadm --assemble --scan to start
the raid and then post when it works.

Thanks, BobH
