After adding geom_raid_load="YES" to my /boot/loader.conf, it still didn't create the device on bootup. I had to manually create the label with graid. After that it created /dev/raid/ar0 for me and I could mount the volume. Only thing which I've trying to understand is the last message below about the integrity check failed. I've found other posts on this but when I dig into my setup, I don't see the same problems that are illustrated in the post and am at a loss for why that is being stated. Also, on other posts I think it was (raid/r0, MBR) that people were getting and trying to fix. Mine is (raid/r0, BSD) which I cannot find reference to. I have a feeling it has to do with the geometry of the disk or something. Everything else seems fine... I admittedly only use this volume for scratch space and didn't have anything important stor

It is not related to geom_raid, but to geom_part. There is something
wrong with your label. You may set kern.geom.part.check_integrity sysctl
to zero do disable these checks. AFAIR it was mentioned in 9.0 release
notes.
