<p class="MsoNormal"><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi All,</span><span lang="EN-US">
<br>
<br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">I was going through the following blue print, NetApp proposed and implemented in its driver (NetAppNFSDriver - cinder/volume/drivers/netapp/nfs.py</span><span lang="EN-US">
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">) a while back (</span><span lang="EN-US"><a href="https://review.openstack.org/#/c/41868/"><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">change</span></a></span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">):</span><span lang="EN-US">

<br>
<br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">It looks quite an interesting and valuable feature for the end customers.</span><span lang="EN-US">
<br>
</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Can we make it part of the base NfsDriver (cinder/volume/drivers/nfs.py)? so that the customers using the base NFS driver can benefit and also other drivers inheriting from
this base NFS driver (e.g. IBMNAS_NFSDriver, NexentaNfsDriver) can also benefit.</span><span lang="EN-US">

</span><span lang="EN-US" style="font-size:10.0pt;font-family:"Arial","sans-serif"">Please let me know your valuable opinion.</span><span lang="EN-US">
