You can't export non-ffs filesystems with NFS, and it isn't documented

Hi,

I just noticed once again you can't export non-ffs filesystems
with NFS. Well you can export them, but after mounting the
partition on the client you won't see any files.

It assume this is not a bug but expected behaviour. But on the
other hand this isn't mentioned in the documentation.

Perhaps it would also be nice if mountd would complain while you
attempt to export a non-ffs filesystem.

I can't verify this behavior... mounted a msdos filesystem (usb stick)
and exported it via nfs. i could mount and view all files on target nfs
client. (server and client both -current).

Odd...

Could you be so kind to show me the lines of the msdos partition
in /etc/fstab and in exports?

I have:

~% grep msdos /etc/fstab
/dev/sd0a /mnt/usb msdos rw,nodev,nosuid,noatime,noauto 0 0

~% grep usb /etc/exports
/mnt/usb/ -mapall=han:nfs marsupilami

I haven't been following this thread but trailing slashes can sometimes mean
things. Have you tryed removing it?

ie.

/mnt/usb -mapall=han:nfs marsupilami

Yes I have tried that as well. I have tried all sorts of logical
and illogical things. It didn't change the outcome though.

/dev/sd1i /umass msdos rw,noauto,nodev,nosuid,noexec 0 0

/umass -maproot=root dual

(dual is the hostname of the nfs-client)

Have you successfully mounted this? Shouldn't it be /dev/sd0i?

Odd... It still doesn't work.
