<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri",sans-serif;color:#1F497D;mso-fareast-language:EN-US">Doing Stuff to disks aggressively is often not a good idea (!) Urging an admin to do Stuff to disks just at the moment they are under
pressure to press “deploy” is a less bad idea that comes with added complexities, as discussed well on this thread. A third option is simply to tell folks what you did. A ‘silent ignore’ of disks is not that. Naïve or not, I hope ‘documenting ignores’ for
clarity is a low impact enhancement for deepsea relative to other approaches.<o:p></o:p></span></p>
