NFS exports

Installation and configuration was a snap ; and in 10 minutes we had the filesystem exported and mounted on the target system.

It involved the following:

1. package - nfs-user-server – the description from the
   package had these notes. hasn't been an issue for us so far.

   This package contains all necessary programs to make your Linux machine act as an NFS server, being an NFS daemon (rpc.nfsd), a mount daemon (rpc.mountd).Unlike other NFS daemons, this NFS server runs entirely in user space. This
   makes it a tad slower than other NFS implementations, and also introduces some awkwardnesses in the semantics (for instance, moving a file to a different directory will render its file handle
   invalid). There is currently no support for file locking.

2. Portmap had to be reconfigured to take out the loopback.
   

   • File changed:/etc/default/portmap
     

   • #OPTIONS="-i 127.0.0.1"

3. Edited /etc/exports to add directory to export

   • /mnt/data3 target.mount.host (rw,sync,no_root_squash)

   • no_root_squash is to allow for root on the remote system to
     be root on the exported fs; we needed this to be able to write from
     tape extraction.

4. Restarted nfs-user-server and portmap.

5. showmount -e to confirm exports were successful
