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?

    I figured it out. I need to run resize2fs afterwards. I ran sudo resize2fs /dev/mapper/luks-5e5f911c... and that solved the issue.

      Yup. This applies to filesystems regardless of whether they’re in an encrypted partition it not… You need to grow the FS size to fill the partition.

      For other FS types it’s:

      xfs_resize /path/to/device

      btrfs filesystem resize max /path/to/mountpoint

      For LVM you may also need to first pvresize and then lvresize

      Not sure about JFS or others
