Ugh, ataraid.
If you skip the first 1MB or thereabouts, do the drives have exactly
the same contents?
I suppose you say that ataraid is not usable in production...
I will try to convert ataraid in raidframe configuration as soon as
possible.
I am not advocating that, I'm trying to gather information. Do the
drives actually have the same contents at this point in time, or not?
I don't know as this server if far away and doesn't reboot anymore.
Kernel doesn't find /sbin/init. I will try to reboot this server next
friday (CET). And after, I will check if both drives have same contents.

Hello,
I cannot verify if both disk of my ataraid have same contents. But I
have done some tests on two new NetBSD 7 installations with ataraid
(same hardware, same disks).
I have desynchronized raid on the second of these workstations (by
entering in kdb during huge disk I/O and rebooting system without any
sync operation).
First constatation : this system has never tried to resynchronized
raid. It only tried to run fsck at boot.
Second constatation : kernel regulary panics in vfs/ffs subsystem on
second workstation (both disks don't contain same data). It never panics
on first one.
I suspect your explanation is correct. System tries to write on ataraid
and write operation aborts as kernel panics. On next reboot, ataraid
doesn't resynchronize data.
