Running into limitations with the initial space allocation is a common problem, and Linux was ways to add storage while preserving the existing directory structure.
This is generally the same across linux distros. If you used the Fedora Workstation defaults, you are using btrfs, and should read up on btrfs device add (starting with man btrfs-device, and maybe looking for online examples/tutotials). Note that for btrfs a second “balance” step is needed following “device add” to make use of the added space).
