Steps
Installing the SSD
Power off the machine, install the NVMe SSD into the correct slot, and reboot.
Verifying Disk Detection
Confirm that the newly installed 465 GiB NVMe SSD has been properly detected.
root@latte01:~# sudo fdisk -l
...
Disk /dev/nvme0n1: 465.76 GiB, 500107862016 bytes, 976773168 sectors
Disk model: SHGP31-500GM
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
...
Checking Currently Used Disks
You can see that the NVMe SSD (`/dev/nvme0n1`) installed above has not yet been mounted.
root@latte01:~# df -h

Creating a Disk Partition
Follow the steps below to create a partition on the disk identified above.
root@latte01:~# sudo fdisk /dev/nvme0n1
Welcome to fdisk (util-linux 2.37.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
Device does not contain a recognized partition table.
Created a new DOS disklabel with disk identifier 0x66336a6e.
Command (m for help): n
Partition type
p primary (0 primary, 0 extended, 4 free)
e extended (container for logical partitions)
Select (default p): p
Partition number (1-4, default 1): 1
First sector (2048-976773167, default 2048):
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-976773167, default 976773167):
Created a new partition 1 of type 'linux' and of size 465.8 GiB.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
The message `Created a new partition 1 of type 'linux' and of size 465.8 GiB.` will appear, and you must type `w` to actually write the partition.
Checking Disk Status
If you check with `fdisk -l`, you can see that the disk is now listed as a device, unlike before.
root@latte01:~# sudo fdisk -l
Disk /dev/nvme0n1: 465.76 GiB, 500107862016 bytes, 976773168 sectors

Device Boot Start End Sectors Size Id Type
/dev/nvme0n1p1 2048 976773167 976771120 465.8G 83 Linux
Formatting the Partition
Use the following command to check how other file systems are formatted.
root@latte01:~# sudo blkid
/dev/mmcblk2p2: UUID="aa495c97-2344-4d43-a689-b619820a0210" BLOCK_SIZE="4096" TYPE="ext4" PARTUUID="f60e2f86-337d-4890-bfbd-fc6555e075f0"
/dev/loop1: TYPE="squashfs"
/dev/nvme0n1p1: PARTUUID="66336a6e-01"
/dev/mmcblk2p1: UUID="986C-B2FC" BLOCK_SIZE="512" TYPE="vfat" PARTLABEL="EFI System Partition" PARTUUID="995635dd-2919-4051-9388-abfd4e42d81e"
root@latte01:~# df -h
Filesystem Size Used Avail Use% Mounted on
tmpfs 777M 2.1M 775M 1% /run
/dev/mmcblk2p2 57G 39G 16G 72% /
We want to match the format of `/dev/mmcblk2p2`, which uses the most storage. Therefore, we will format the new disk with `ext4` as well.
Proceed with formatting.
root@latte01:~# sudo mkfs.ext4 /dev/nvme0n1
mke2fs 1.46.5 (30-Dec-2021)

Mounting the Disk
Create a folder to use the disk.
root@latte01:~# mkdir -p /data1
Add the auto-mount information for the new disk to /etc/fstab.
data1
UUID=482ee0df-9d2d-4959-9026-de7206de5aaf /data1 ext4 defaults 0 0
After adding:
/etc/fstab: static file system information.
#
Use 'blkid' to print the universally unique identifier for a
device; this may be used with UUID= as a more robust way to name devices
that works even if disks are added and removed. See fstab(5).
#
<file system> <mount point> <type> <options> <dump> <pass>

Applying the Mount
sudo mount -a
Verifying the Result
root@latte01:~# sudo mount -a
root@latte01:~# df -h
