In the earlier versions of kernel 2.4 you could enableboot support and auto detect support under raid. This options is not there any more. Is it still possible because I am doing the exact same setup for a software raid system as I did with Slackware 8 and kernel 2.4.5 and are now using Slackware 9 and it seems the md devices are not detected as with my slackware 8 system.

Thanks

I recall the kernel option to disable and enable the autodetect feature. But I thought it was on the latest 2.2.x kernels. The 2.4.x kernels I thought always detected md devices if the md support was builtin to the kernel. But my memory could be faulty. If you are starting from scratch, did you remember to set the partition type correctly to raid autodetect? The default bare.i kernel for Slack 9 does have md support included. I do not know about the other kernels though. If you have built custom kernel then make sure the md support for your setup is included in the kernel and it is actually booting.

Once you have actually built the raid device, it should appear in the /proc/mdstat listing upon booting.

Did use bare.i, only get L 01 01 01 line after line when trying to boot from the new device.

Are you attempting to boot the md device directly with lilo?

Yes, I am still learning.

I haven't tried that as yet. I still like the comfort of knowing that I have regular maintenance partition to boot from and then setup my lilo.conf to boot the same kernel but with a different root. So I create a 2 GByte regular partition for a maintenance platform. But when I was reading in the recent lilo docs, if I recall, it should support booting the md device. But your error messages are lilo related and not kernel related because the kernel hasn't booted yet. That is what the message is indicating that the lilo boot loader is not loading. You might want to review the lilo docs to see what you are suppose to set the lilo.conf to write to. It may require the MBR of the first bootable hard disk to load the kernel. Once the kernel is loaded it will detect the md device, then the root device should of been passed to the kernel for it to initiate the init system and continue the boot.

Perhaps it will help.
