Can I re-export via NFS a partition that is NFS mounted on the server?

[zephrant]

I have a DHCP/PXE server behind a firewall. It mounts partitions on the file server on the corp. network on the other side of the firewall. Every box that PXEs also mounts partitions on the main file server.

I was hoping I could change them to mount from the DHCP/PXE server, so that server could cache and cut down on the requests through the firewall, as well as the sessions that the firewall must track.

But it seams a little strange to try to export directories that are simply NFS mounts on another server already.

I'm running Fedora 8, and get these errors on the server:

[root]# exportfs -ra
exportfs: Warning: /mnt/home does not support NFS export.
exportfs: Warning: /tftpboot does not support NFS export.

Other directories export fine.

Is this possible?

kinda hacky, but maybe try making a symlink to the nfs share, and then exporting the symlink? I'm not sure, i would like to think you could re export though

A good thought-

My exports file has this line in it:

/mnt/images     172.30.*(rw,async,secure,no_root_squash)

which is a link to /tftpboot already.

[root]# ll /mnt
drwxr-xr-x 53 root root  8192 2010-01-08 13:20 home
lrwxrwxrwx  1 root root    10 2008-10-02 17:06 images -> /tftpboot/
