exportfs: Warning: /path/to/dir does not support NFS export.

hi,

exportfs outputs the following error upon restart or after editing /etc/exports.

'exportfs: Warning: /exports does not support NFS export.'

here is my info and configs.

On second thought, here is the contents of the webpage.

Start with: apt-get install nfs-kernel-server

Basically, the server will not export the directory /exports. Is there anyway to fix this?

Same here. Cannot get my NFS to work this way. I am on Lucid Lynx.

Perhaps the bind mount is the issue...? I'm not sure. What are you doing that's similar to the OP?

And to the OP, did you ever sort this out?

I was just having the same problem and stumbled upon this post. I am able to use NFS with several folders, but not on a folder in my home directory. My guess now is that it's because I have an automatically encrypted home folder...

When I created another folder outside my home folder (i.e., change /home/user/folder to /home/folder) it worked just fine.

I'm using both ext3 and ext4 for the shares, btw.

I have a similar problem on a sheevaplug. For me the root cause is that the main nfs4 export directory is situated on an ext4 filesystem. If I move it to an ext3 filesystem all problems are gone. It is fully described in following debian bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=602956

Although my 10.04.1 LTS server complains the same:
exportfs: Warning: /var/lib/vmware/Virtual Machines does not support NFS export.
...done.
* Starting NFS kernel daemon
...done.
It works nonetheless: my 10.10 desktop client connects without any troubles!

(let me note: all these systems run on intel CPUs)

I was having this exact same problem. In my case I was trying to export a directory that was already mentioned in my autofs configuration (specifically /etc/auto.direct). This was because I'm migrating files between two servers and I forgot to delete auto mounts from my "New" file server.

Removing the directory from /etc/auto.direct.
