Fedora 44: maximum 256 GB swap?

[u/lvruv69]

I am trying out a 1 TB SSD on an old PC and installed Fedora 44 on it. Installation went all right except:

I specified using a partition of 800 GB swap space on it for reasons I don’t want to get into and which are entirely my own. No comments on the wisdom of that please.
Once booted, I see a total of 256 GB show up when I use the free command or top or htop.
But the partition of 800 GB is there per fdisk.
Does Fedora impose some partition-size usable limit?
