...well, no, it's weirder than that.
I was working with NetBSD/sun3 and somehow managed to create a
filesystem that fsck thought was damaged but couldn't fix. It would
always say
BLK(S) MISSING IN BIT MAPS
SALVAGE?
and then, when I say "y", would write on the disk...but then running
fsck again produces the same "error". And I have reason to think that
the filesystem actually was corrupt; I twice got a panic ("freeing free
block", IIRC), and when cleaning up afterwards I found this weirdness.
Then, before running off at the keyboard about it, I moved the disk to
a SPARC and tried fsck there. It produced no complaints at all, and
had no problem using the filesystem.
This is just too weird. I have no idea how reproducible this may prove
to be...anyone have any ideas? Does NetBSD/sun3 DTRT with memory
parity errors (ie, could this be an undetected memory error)?
