Clonezilla, automatically resize GPT partition table.
Nothing better than that.
If you use an LVM or a modern filesystem like BTRFS, you can just increase it afterwards, so that your partitions grow to the entire available space.
This is not possible with regular static partitions.
Otherwise afaik you can delete it and recreate it to fill up all usable space.
But well, just use BTRFS or maybe LVM.
Would deleting it also delete the data on it? What is the point of automatically resizing them then?
No it doesnt. Partitions need to start at the exact bit they start, but can end at something bigger.
Thats the trick.
Using gdisk you would print the table, make a photo, delete it, create them new and set the max for the storage partition (if you use BTRFS or LVM like a normal person) to the original start, but max available end
Then you print again and verify and write to apply the changes.
Then there is space but the partitions need to fill that up still, with btrfs on Fedora that would be
sudo btrfs resize max /I think
