Use Case

Configuring Persistent Storage​

Mounting /dev/vdb to /home/example/jetbackup5

creating a filesystem on the disk​

List available disks:

lsblk -f

Example disk: /dev/vdb

Create a GPT partition table, create a partition, and format it as ext4:

danger

This process will destroy all existing data on the disk.

Input:

parted /dev/vdb --script mklabel gpt
parted /dev/vdb --script mkpart primary ext4 0% 100%
mkfs.ext4 /dev/vdb1

This creates an ext4 filesystem on the empty disk so it can be used for storage.

creating the mountpoint directory​

Input:

mkdir -p /home/example/jetbackup5

This directory will be used as the mount target.

mounting the disk for the first time​

Input:

mount /dev/vdb1 /home/example/jetbackup5

The disk is now mounted and ready to use.

getting the UUID for fstab​

Input:

blkid /dev/vdb1

Output:

/dev/vdb1: UUID="3f1c0b8f-7b1a-41cd-8e1c-635dbe22c291" TYPE="ext4"

This shows the UUID that will be used for persistent mounting.

adding the entry to fstab​

Input:

echo 'UUID=3f1c0b8f-7b1a-41cd-8e1c-635dbe22c291  /home/example/jetbackup5  ext4  defaults  0  2' >> /etc/fstab

This ensures the disk mounts automatically at every boot.

testing the fstab configuration​

Input:

mount -a
