Mechanism / Steps to clean up DD890 SPACE
# filesys clean status
Cleaning finished at 2015/03/15 22:46:30.
it looks some kind of mechanism has been already in-placed.
Can somebody please share with me where and how can I find the configuration?
There is no "gpddboost" on this DD, then what are steps to determine what data could be deleted, and what commands to delete them?
Thanks for sharing!

You can run something like
foo@bar# filesys clean show config
80 Percent Throttle
Filesystem cleaning is scheduled to run "Sun" at "0900".
Above you see that cleaning is scheduled to run on Sunday at 9am with 80% CPU throttle. df command will show you how much is already mark for cleaning and filesys clean now command will start cleanup process right away.
I'm not sure where did you come up with gpddboost, but as names suggests, that is GreenPlum ddboost plugin and irelevant for actual cleanup process. You can find details in How to delete data and reclaim space from Data Domain System using gpddboost and nfs exports. Even there, you must delete stuff which has been written using API/module command (gpddboost) and this only marks data to be deleted on DD (it does not delete it as that is part of garbage collection process) just as this is done automatically via any backup application.
