Subject: exporting a MFS partition via NFS
Mime-Version: 1.0

Hi,

I'm running FreeBSD 2.2.6 with the MFS option compiled in the kernel.  
I've created an MFS partition that I would like to export via NFS.  
The MFS partition is mounted on "/memmap".  I have the following lines 
in /etc/exports:

/       -alldirs -maproot=root -network 10.0.2.0 -mask 255.255.255.0
/memmap -alldirs -maproot=root -network 10.0.2.0 -mask 255.255.255.0

When I try to mount MFS the partition from a Linux box, I get the 
following error:

[root@dev /mnt]# mount 10.0.2.39:/memmap /mnt/drive
mount: wrong fs type, bad option, bad superblock on 10.0.2.39:/memmap,
       or too many mounted file systems

I am able to mount the root partition.  Is there any way to export the 
memory mapped file system?

Thanks,
-Peter Weck

We want to run hlfsd (part of the BSD automounter utilities suite),
which seems to require the ability to disable the attribute cache on the
NFS filesystem it creates.  According to the documentation one can force
it to run anyway, but since it operates by returning different values
for the same symbolic link depending on how it's accessed, any amount of
caching may cause incorrect values to be returned.

I assume disabling the cache is possible under FreeBSD, but hlfsd and I
just don't know how.  Please enlighten us. :-)

Thanks ...
