Dear List,
<div class=""><br class="">
</div>
<div class="">I’m currently working on a self service portal for managing NFS exports of ISS. Basically something very similar to OpenStack Manila but tailored to our specific needs.</div>
<div class="">While it was very easy to do this using the great REST API of ISS, I stumbled across a fact that may be even a show stopper: According to the documentation for mmnfs, each time we</div>
<div class="">create/change/delete a NFS export via mmnfs, ganesha service is restarted on all nodes. </div>
<div class=""><br class="">
</div>
<div class="">I assume that this behaviour may cause problems (at least IO stalls) on clients mounted the filesystem. So my question is, what is your experience with CES NFS export management.</div>
<div class="">Do you see any problems when you add/change/delete exports and ganesha gets restarted?</div>
<div class=""><br class="">
</div>
<div class="">Are there any (supported) workarounds for this problem? </div>
<div class=""><br class="">
</div>
<div class="">PS: As I think in 2017 CES Exports should be manageable without service disruptions (and ganesha provides facilities to do so), I filed an RFE for this: <a href="https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=111918" class="">https://www.ibm.com/developerworks/rfe/execute?use_case=viewRfe&CR_ID=111918</a></div>

</div>
<div class="">Many thanks in advance.</div>
<div class="">Best Regards,</div>
<div class="">Stephan Peinkofer</div>
