llish, and/or you don't need the backups -- create independent
filesets, copy/move/delete the data, rename, voila.

The -P option may be a very good workaround, but I still have

"converting from one fileset to another" --- sorry there is no such thing.
Filesets are kinda like little filesystems within filesystems. Moving a
file from one fileset to another requires a copy operation. There is no
fast move nor hardlinking.

Here is one big reason independent filesets are problematic:

Table 43. Maximum number of filesets
Version of GPFS
Maximum Number of Dependent Filesets
Maximum Number of Independent Filesets

As I understand it,
mmbackup calls mmapplypolicy so this stands for mmapplypolicy too.
mmapplypolicy scans the metadata inodes (file) as requested depending on
the query supplied.
You can ask mmapplypolicy to scan a fileset, inode space or filesystem.

Thanks for the explanation Mark and Luis,
It begs the question: why filesets are created as dependent by
default, if the adverse repercussions can be so great afterward? Even
in my case, where I manage GPFS and TSM deployments (and I have been
around for a while), didn't realize at all that
When I see "independent fileset" (in Spectrum/GPFS/Scale) I always think
and try to read that as "inode space".
An "independent fileset" has all the attributes of an (older-fashioned)
dependent fileset PLUS all of its files are represented by inodes that are
in a separable range of inode numbe
