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. Regards, JKB
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.
