(Linux) Mounting Disks

This is so difficult every time. Let's note this down.

---

1. lsblk to identify the drives

lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINT

Look for drives like /dev/sdb, /dev/sdc, etc., that don’t have a mountpoint and no filesystem (FSTYPE empty).

2. Partition drives

sudo parted /dev/sdb -- mklabel gpt
sudo parted /dev/sdb -- mkpart primary ext4 0% 100%
sudo parted /dev/sdc -- mklabel gpt
sudo parted /dev/sdc -- mkpart primary ext4 0% 100%

3. Format drives

sudo mkfs.ext4 /dev/sdb1
sudo mkfs.ext4 /dev/sdc1

4. Get UUIDs

sudo blkid
#/dev/sdb1: UUID="abcd-1234" TYPE="ext4"
#/dev/sdc1: UUID="efgh-5678" TYPE="ext4"

5. Create mount points

sudo mkdir -p /mnt/disk2
sudo mkdir -p /mnt/disk3

6. Edit fstab to create persistent mounts

sudo nano /etc/fstab

UUID=abcd-1234  /mnt/disk2  ext4  defaults  0  2
UUID=efgh-5678  /mnt/disk3  ext4  defaults  0  2

7. Mount!

sudo mount -a
