First, use lsblk to see the raw partitions:
|
1 2 3 4 5 6 7 8 9 |
# df -hT Filesystem Type Size Used Avail Use% Mounted on /dev/nvme0n1p1 xfs 20G 2.8G 18G 14% / # lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT nvme0n1 259:0 0 40G 0 disk ├─nvme0n1p1 259:1 0 20G 0 part / └─nvme0n1p128 259:2 0 1M 0 part |
Note how the partition at 259:1 is only 20GB, while the entire disk at 259:0 is 40GB. A partition resize is required in this case.

For an EXT4 filesystem, use the resize2fs command instead:

sudo resize2fs /dev/nvme0n1p1 |
