<div>Hi,<br>
</div>
<div><br>
</div>
<div>showmount -a should do the trick, however the manpage notes that:</div>
<div><br>
</div>
<div>-a or --all</div>
<div> List both the client hostname or IP address and mounted directory in host:dir format. This info should not be considered reliable. See the notes on rmtab in rpc.mountd(8).<br>
</div>
<div><br>
</div>
<div>showmount -d could also be an option:</div>
<div><br>
</div>
<div>-d or --directories<br>
List only the directories mounted by some client.<br>
</div>
<div><br>
</div>
<div>Best regards,</div>

<p class="x_MsoNormal">This is probably a dumb question, but I could not find it in the documentation. We have certain NFS exports that we suspect are no longer used or needed but before removing we’d like to first check if any clients are currently mounting
them. (Not just what has access to those exports.) Are there commands that will show this?
