Well, I happen to be using Fedora as engine/hosts, but when it comes to the NFS-server, why settle for anything less, right?:) I imagine you´re in it for the same reason as me too; "the last word in filesystems"...<div class="im">

threads running again, if this option is used.<br>
<br>
<br>
so far, i was able to reload the exports list twice, without any random suspended vm. lets see if this is a real solution or if i just had luck two times.<br>

<blockquote>It would seem as if we are on the same boat:) Actually I hadn´t thought about it before, but you´re right; issuing a "service mountd reload" does pause a large number of VM´s, frickin annoying really. I mean, the NFS server doesn´t care what or
who it´s serving, you could be creating a new export for a completely different system, and not even have oVirt in mind before customers start to call, wondering why their VM´s have stopped responding!?<br>

OK, so we´re not using the same versions, -STABLE != -RELEASE, and I only use -RELEASE. But that explains it. I guess I can wait for 9.2-RELEASE to get rid of that nuisance. Thanks for the info!<span class=""><font color="#888888"><br>
