<p class="MsoNormal"><span style="color:#1F497D">When we want to remove filesets we link them in an area that isn’t exported by CIFS or NFS. This allows us a grace period where the users most definitely cannot access the files before we delete them permanently.<o:p></o:p></span></p>

<p class="MsoNormal">This is more a TSM question than GPFS but it involves GPFS to a point so I hope I’m ok asking this.<o:p></o:p></p>
<p class="MsoNormal"> <o:p></o:p></p>
<p class="MsoNormal">I’ve unlinked a fileset and relinked it at a different junction point. Will this cause TSM to see a “new” fileset and back up all its content? This is very undesireable so if I need to put it back where it belongs then I need to do this
before tonight.<o:p></o:p></p>
