This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,
Post an idea.
Get feedback from the IBM team and other customers to refine your idea.
Follow the idea through the IBM Ideas process.
Welcome to the IBM Ideas Portal (https://www.ibm.com/ideas) - Use this site to find out additional information and details about the IBM Ideas process and statuses.

We're seeing requests for customers running Commvault that they need support for hole punching to free up space in already allocated files.
Please support deallocating space in files trhough the FALLOC_FL_PUNCH_HOLE and FALLOC_FL_KEEP_SIZE flags of fallocate().
Ref: http://man7.org/linux/man-pages/man2/fallocate.2.html
This should then also be exposed through SMB mounts, which I believe samba will handle automatically once it sees the flag is supported. And hopefully also through NFS-ganesha.
