GFS2 can theoretically go much higher, but we only recommend up to 100TB
for a single namespace.

We publish what we can test and verify. Right now, we've tested up to
100TB.  Beyond that, we think it's smarter to break it up.

If you have a reason to go over that, please open a "feature request"
support ticket, and it probably wouldn't hurt to contact your sales team
and let them know what's going on and why you need it.  We are
customer-driven, so if we need to make changes in our support
boundaries, we need to hear it!

Nothing stops you from making a bigger one. It's just that it's not
supported and if you run into issues that look related to the size,
we'll probably ask you to reproduce them on a < 100TiB namespace.
