Mounting Block Volume

I. Mounting a Brand New Block Volume

When mounting a brand-new block device (without any data), follow these steps:

1. Check the Current Block Devices

Before mounting, confirm the block devices already present on the system.

lsblk

Use lsblk to view all block devices and their mount statuses, for example /dev/vdb.

---

2. Format the Block Device

Use the code below to format your block device:

mkfs.ext4 /dev/<TARGET>

• <TARGET>: name of the block device, e.g., vdb

• Example file system: ext4

• ❗️ If the device already contains data, do not format it or data would be lost.

---

II. Mounting an Existing Block Volume with Data

Whether the device is newly formatted or contains existing data, the following steps for mounting are the same.

1. Verify the Block Device Name

After successfully mounting, the block device typically appears as something like:

/dev/vdb

2. Create a Mount Directory

Create a directory to mount the disk:

mkdir /mnt/<DIR_NAME>

• <DIR_NAME>: The name of the directory you wish to use, e.g., data.

3. Mount the Block Device

Mount the block device to the specified directory:

mount /dev/<TARGET> /mnt/<DIR_NAME>

e.g.

mount /dev/vdb /mnt/data

---

III. (Recommended) Configure Auto-Mount on Boot

To ensure the Block Volume is automatically mounted after system reboots, add it to the /etc/fstab file.

Add fstab Configuration

echo "/dev/<TARGET> /mnt/<DIR_NAME> ext4 defaults,nofail 0 0" >> /etc/fstab

e.g.

echo "/dev/vdb /mnt/data ext4 defaults,nofail 0 0" >> /etc/fstab

PARAMETER	DESCRIPTION
defaults	Use default mount parameters
nofail	Even if the disk does not exist, it does not affect system startup
0 0	Do not perform dump and fsck checks
