I had something similar on a software based RAID controller on my Intel S5000PSL
motherboard when I just went from 8.2-RELEASE to 9.0-RELEASE. 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 st
or
ed
on it so I wasn't worried about experimenting or losing data.

GEOM_PART: integrity check failed (raid/r0, BSD)
Any ideas on the integrity check anyone?
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.
Thanks for responding, Alexander. I also found that information about that
sysctl variable, however I was trying to determine if something is actually
wrong, how to determine what it is and ultimately how to fix it so it passes
the check. I'd rather not ignore errors/warnings unless it's a bug. Again, I
have no data of value on this partition, so I can do anything to fix it. Just
not sure what to do or look at specifically.
First thing I would check is that partition is not bigger then the RAID
volume size. If label was created before the RAID volume, that could be
the reason, because RAID cuts several sectors off the end of disk to
store metadata.
