[gpfsug-discuss] Converting a dependent fileset to independent

To help make sense of this, one has to understand that "independent" means 
a different range of inode numbers.

If you have a set of files within one range of inode numbers, say 
3000-5000 and now you want to move some of them to a new range of inode 
numbers, say 7000-8000, you're going to have to create that new range as a 
new independent fileset, and then move (copy!) the files to the new 
fileset.  And then rename directories so that you can once again refer to 
the files by the pathnames that they "used to" have.

During the copying and renaming, you would have to make sure there are no 
applications trying to access those files and directories.

Hi all,
 
Is there any way, without starting over, to convert a dependent fileset to 
independent?
 
My gut says no but in the spirit of not making unnecessary work I wanted 
to ask.
 
Also, the documentation states that I should see a “dpnd” next to a 
dependent fileset when I run mmlsfileset with -L; this is not the case 
even though the parent fileset is root in this case.
 
[root at nsd bin]# mmlsfileset gpfs studentrecruitmentandoutreach -L
Filesets in file system 'gpfs':
Name                            Id      RootInode  ParentId Created
