Here’s what I did: I bought a new 512 GB SSD to replace my old 256 GB SSD, which was getting full. I put the new SSD in an NVME to USB adapter and then booted to a Fedora 38 live USB and cloned the old drive into the new drive using dd if=/dev/nvme0n1 of=/dev/sda. Then I used gparted to expand the LUKS partition to cover the rest of the disk. I did not have to unlock the encryption for this. After that, I powered off, removed the 256 GB SSD and installed the 512 GB SSD, then booted normally. I did not erase either of the SSDs.

Now when I get into Fedora 38, GNOME Disks reports that /dev/mapper/luks-5e5f911c... is a 511 GB ext4 partition with 80 GB free, and /dev/nvme0n1p3 is a 511 GB LUKSv2 partition, but when I run df, this is what I see:

nate@redgate:~$ df / -h
Filesystem                    Size  Used Avail Use% Mounted on
/dev/mapper/luks-5e5f911c...  233G  159G   63G  72% /

What did I do wrong?

    Did you expand the filesystem itself?

    You go from physical (your dd) to encrypted (luks) to lvm(if used) to your filesytem itself.

    You probably have btrfs so check out Resizing btrfs

    Edit: I can read, you have ext4 :)

    Check out resize2fs, IIRC it can do it live on a mounted partition
