On the page you mention, it states clearly: "[...] and booting from softraid devices isn't supported on all of them. It's currently only possible to boot from RAID1, RAID5 and crypto volumes on i386, amd64 and sparc64." The same in the manpages: http://man.openbsd.org/?query=boot=0=8=default=OpenBSD-current As this already works for me on several systems, i assume that something with your process is wrong here. Or you messed up your upgrade (yes, i upgraded some of the machines). Hth, Marc

What you propose is wrong, but you found it helped you...so sounds like there's a problem with your process. What did you do, what did you expect to happen, what did you see happen? Nick.
Manual update
Hi All, I recently installed 6.0 and was struggling to get my softraid0 stripe to build properly and or boot. I went over section 14 carefully and did some research. The part that I found was missing was the creation of a 100 meg partition on the A slice and how to successfully create a bootable raid stripe. (I'm sure there is something somewhere that I missed, but I thought it would be awesome to include step #2 and #3 in the raid setup) Target https://www.openbsd.org/faq/faq14.html#softraid Source http://undeadly.org/cgi?action=article=20111002154251 #1 - is kind of a question really. My issue was it took me several times to get my raid "perfect" during the process every failed attempt would result in portions of the raid remaining intact. IE fdisk would see RAID partitions that were not wiped or bioctl would think parts of the stripe were degraded etc.. ultimately my solution was to zero fill all of the disks and start fresh..
