Re: Corrupting Files
I have tried removing softdep from the mount options, but from the
results of last night it is still happening, if not worse.
Currently disabled write-back cache on all 4 HDDs and see if it helps.
We also just paniced. fsck takes about 2 hours.
If it were a 48bit LBA, or generally bad partitioning I would have
expected much larger corruption, rather than a few bytes in the middle
of files ..?
So far, it seems to be confined to wd2 and wd3. I am re-testing
everything on wd0 and wd1 just to be sure.

What's the disk caching setup--per "dkctl wd0 getcache" (or
whatever applies given the disk you're using: "wd1", "scsictl
sd0 ...", etc.)?
And, if the write-back cache was enabled, does disabling it
(e.g., "dkctl wd0 setcache r") change the behavior?
