Hello again,
I got a faast reply to my question!

Thanks go to:

It was not clear to me that a clone fileset has to reside on the SAME advfs
domain of the fileset to be cloned.

With this constraint it seems that between 5% to 10% of the domain has to
be free to create the clone fileset, and of course has to be deleted as
soon as possible, after backup, to make the space available.


Follows my original question:
