Moving data between filesets is like moving files between file systems.
Normally when you move files between directories, it’s simple metadata, but
with filesets (dependent or independent) is a full copy and delete of the old
data.

Subject: [EXTERNAL] [gpfsug-discuss] gpfs filesets question
I have filesets setup in a filesystem...looks like:
[root@cl005 ~]# mmlsfileset home -L
Filesets in file system 'home':

root 0 3 -- Tue Jun 30 07:54:09

I beleive these are dependent filesets. Dependent on the root fileset.
Anyhow a user wants to move a large amount of data from one fileset to another.
Would this be a metadata only operation? He has attempted to small amount of
data and has noticed some thrasing.
