That did it! But now it won't let me umount that, even when there
are no processes accessing it.
# mount /dev/wd0l /mnt
# du /mnt
...
# umount /mnt
umount: /mnt: Device busy
# lsof | grep mnt
#
Very strange. I forcibly umount'd, and redid this a few times, so
it's repeatable. I can successfully mount, du, and umount another
ext2fs partition, but not this one. Any ideas?
Thanks!
