How To Add NFS To XenServer Easily?

The NFS server is pre-installed on a new XenServer installation. Therefore, we only need to set up NFS export rather than install the NFS server by ourselves. Here, we’ll see how to configure NFS export on XenServer. Also, we export /export directory using NFS. Let’s look into the steps:

1. On the xterm command prompt, use the following commands:

# vi /etc/exports

# exportfs -a
# service portmap start
# service nfs start
# chkconfig portmap on
# chkconfig nfs on

2. To be able to export the local storage, we must now complete one crucial final step. By default, portmap will only bind to the loopback interface (with the -l option), preventing any other external host from mounting its storage through NFS. As seen below, we can verify this behavior. The XenServer host’s IP address is 192.168.212.205.

# showmount -e localhost
# showmount -e 192.168.212.205

3. As we can see, the first command correctly displays the export list for localhost, however, the second command fails for the aforementioned reason, displaying the following message:

4. To remove this portmap restriction, change /etc/sysconfig/portmap as follows:

PMAP_ARGS=""

5. Restart the NFS service after the change.

# service portmap restart
# service nfs restart

6. Run again to confirm that the export is functioning properly.

$ showmount -e 192.168.212.205

7. Now we can see the export list for the XenServer host 192.168.212.205, this shows that the NFS-export is all set.

Conclusion

The article provides a 7-step method to add NFS to the XenServer. Here, we only set up NFS export rather than installing the NFS server since it is already pre-installed on XenServer installation.
