I see<br> from the changelogs that it should be there. I have setup a lustre<br> filesystem for use in the CAD space for simulations. ModelSim, for<br> whatever reason, is failing to lock files in the its chain of<br> attempted lock mechanisms, and in the end tries and fails to use NFS<br> style locks, or so the CAD guys tell me. I'm curious if this _should_<br> work on 1.6, and if not, is there a relatively accessible 1.8 build<br> with this currently?<br> _______________________________________________<br> Lustre-discuss mailing list<br> <a href="mailto:Lustre-discuss@lists.lustre.org">Lustre-discuss@lists.lustre.org</a><br> <a href="http://lists.lustre.org/mailman/listinfo/lustre-discuss">http://lists.lustre.org/mailman/listinfo/lustre-discuss</a><br> <br> </span></font></blockquote><font face="Verdana, Helvetica, Arial"><span style="font-size:12.0px"><br> </span></font><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">Lustre-discuss mailing list</div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="mailto:Lustre-discuss@lists.lustre.org">Lustre-discuss@lists.lustre.org</a></div><div style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><a href="http://lists.lustre.org/mailman/listinfo/lustre-discuss">http://lists.lustre.org/mailman/listinfo/lustre-discuss</a></div> </blockquote></div><br></div></body></html>
