to create the NSDs. Possible to utilize them to just regenerate the NSDs or is it consensus that the FS is gone? As the system was not in production (yet) I’ve got no problem delaying the release and running some tests to verify possible fixes. The system
was already unmounted, so it is a completely inactive FS across the cluster.<o:p></o:p></span></p>

I have been categorically told by IBM in no uncertain terms if the NSD<br>
descriptors have *ALL* been wiped then it is game over for that file<br>
system; restore from backup is your only option.<br>
<br>
If the GPT table has been "restored" and overwritten the NSD descriptors<br>
then you are hosed.<br>
