nfs export problem configuration not correct

[Tapas Mishra]

I think I missed some thing to specify hence opening this here.


I am trying to export a USB disk partition attached to my computer as
nfs export.
the directory I want to export is

/media/vol2

I created a directory

/mnt/nfs
Installed required nfs packages
nfs-kernel-server nfs-common portmap and other things.

in /etc/exports

/media/vol2/ /mnt/nfs (rw,sync,no_subtree_check)

Now /etc/init.d/nfs

/etc/init.d/nfs-kernel-server restart


* Stopping NFS kernel daemon [ OK ]
* Unexporting directories for NFS kernel daemon... [ OK ]
* Exporting directories for NFS kernel daemon... exportfs: No options
for /media/vol2/ /mnt/nfs: suggest /mnt/nfs(sync) to avoid warning
exportfs: /etc/exports [1]: Neither 'subtree_check' or
'no_subtree_check' specified for export "/mnt/nfs:/media/vol2/".
Assuming default behaviour ('no_subtree_check').
NOTE: this default has changed since nfs-utils version 1.0.x

exportfs: invalid netmask `mnt/nfs' for


What did I miss?
I am doing this on Lucid 64 bit desktop edition.
