Here’s what I did, on the RPi running NetBSD (pi3bsd):
# cd /export/sun
# dd if=/dev/zero of=smallfs.iso bs=1048576 count=404
# vnconfig vnd0 smallfs.iso
# newfs -O 2 /dev/rvnd0
# mkdir smallfs
# mount /dev/vnd0 smallfs
# cat >> /etc/exports
/export/sun/smallfs -maproot=root:wheel ferrari
# kill -HUP `cat /var/run/mountd.pid`
And on the Sun-3/60 (ferrari):
# mkdir /mnt2
# mount pi3bsd:/export/sun/smallfs /mnt2
# cd /mnt2
Then I copied some stuff there and compiled it with stock cc, which uses stock as. From there, I can compile and assemble to my heart’s content.
So something is definitely going wrong in what the server is reporting under NFSv2 for a >2GB volume.
