I've been running openbsd 4.6 for a couple years now with root on softraid, booting off a CF card with a kernel compiled to hardcode root/swap on sd0.
I read about official support for root on softraid: http://www.undeadly.org/cgi?action=article&sid=20111002154251 and got the impression it would just work, particularly the part about "eliminates the need for a custom kernel". However, I just did a test install on a vm with two ide hard drives (wd0 and wd1) configured into a softraid mirror (sd0), and when booting the kernel from wd0a it tries to find the root on wd0a as well, and panics. I was able to get it to boot by either providing the -a option to boot and specifying sd0a as the root, or by compiling a custom kernel with sd0a hardcoded as I did in 4.6. Am I missing something? Based on the web post, I expected the kernel loaded from wd0a to figure out root was on sd0a and boot successfully. Looking at the underlying commit: http://article.gmane.org/gmane.os.openbsd.cvs/108176 It's talking about comparing the rootduid to the softraid volume. I'm not clear where this is coming from, the fstab in sd0a uses duid's, but I don't see how the booting kernel would know about that yet. Anyway, just to clarify my understanding, is it expected in 5.0 to be able to boot softraid root without a custom kernel or using -a? If so, what am I doing wrong? Thanks... -- Paul B.
