<p>Mounting an NFS filesystem is straightforward using CFEngine’s storage promises. The following bundle specifies the name of a remote file system server, the path of the remote file system and the mount point directory on the local machine:</p>

<p>```cf3
body common control
{
bundlesequence =&gt; { “mounts” };
}</p>

<p>bundle agent mounts
{
storage:</p>

<p>“/mnt” mount  =&gt; nfs(“fileserver”,”/home”);  # “/mnt” is the local moint point
                                               # “fileserver” is the remote fileserver
                                               # “/home” is the path to the remote file system
}</p>

<p>body mount nfs(server,source)
{
mount_type =&gt; “nfs”;           # Protocol type of remote file system
mount_source =&gt; “$(source)”;   # Path of remote file system
mount_server =&gt; “$(server)”;   # Name or IP of remote file system server
mount_options =&gt; { “rw” };     # List of option strings to add to the file system table (“fstab”)
edit_fstab =&gt; “true”;          # True/false add or remove entries to the file system table (“fstab”)
}
```</p>

<p>This policy can be found in <code>/var/cfengine/share/doc/examples/example_mount_nfs.cf</code></p>

<p>Here is an example run.  At start, the filesystem is not in /etc/fstab and is not mounted:</p>

<p><code>
# grep mnt /etc/fstab # filesystem is not in /etc/fstab
# df |grep mnt # filesystem is not mounted
</code></p>

<p>Now we run CFEngine to mount the filesystem and add it to /etc/fstab:</p>

<p><code>
# cf-agent -f example_mount_nfs.cf  
2013-06-08T17:48:42-0700    error: Attempting abort because mount went into a retry loop.
# grep mnt /etc/fstab
fileserver:/home 	 /mnt 	 nfs 	 rw
# df |grep mnt
fileserver:/home 149912064 94414848  47882240  67% /mnt
# 
</code></p>

<p>Note: CFEngine errors out after it mounts the filesystem and updates
/etc/fstab.  There is a ticket https://cfengine.com/dev/issues/2937
open on this issue.</p>
