After replacing all the disks with new ones, the same crash popped up again on that filer, after two more days of heavy reads and writes. I rebooted it ten times in a row... kernel panic every time on "../driver/disk/disk.c:2633: Assertion failure" right after the "Recomputing parity in NVRAM" message (I assume that means it never gets around to replaying the WAFL logs?).
Did it ever mention dumping the NVRAM? Or is it always crashing before it ever replays NVRAM? I think I understand what you're saying above but you didn't mention any other error messages from the other reboots so I wanted to be sure.
Call Netapp tech support, was told an on-call engineer would call back... haven't heard anything back yet. *sigh*
It sounds like the disks themselves have become corrupted in such a way that it's dying on initialization... they will probably have you boot off floppy to wack the filesystem, and/or dump the NVRAM manually.
The fact that it continues to be the same machine leads me to think that swapping out the NVRAM card and/or the SCSI cards may be in order.
But, I'm no expert support person and I don't have access to the code, so Netapp may have already figured out what this bug is and the solution is totally different. :)
