}Could you recompile fsck_lfs with '-g' ('make CFLAGS=-g' in fsck_lfs),
}and run the resulting binary under gdb ?
}(gdb ./fsck_lfs
}run /dev/raid0a
})

(gdb) run /dev/raid0d
Starting program: /stuff/NetBSD/src/sbin/fsck_lfs/./fsck_lfs /dev/raid0d
** /dev/rraid0d (NO WRITE)

Program received signal SIGSEGV, Segmentation fault.

}In theory, you shouldn't need to fsck an LFS filesystem, so you can put
}'0 0' in the fstab for it (it's what I have on my machine). 

Cool.

I copied the src, xsrc & pkgsrc trees to this partition, and I don't
understand what df is doing.

During copy:
# while 1
while? df /stuff
while? sleep 20
while? end

Things finished copying, and I deleted some stuff, then:

5 hours later:

This started out near 85GB, I'm confused.
