Mount the device to the specified directory

mount /dev/vdb1 /home

Take the example of mounting to the /home directory.

Save to file system table /etc/fstab

When the system reboots, the system automatically reads information from this file and automatically mounts the file system specified in this file to the specified directory.

echo /dev/vdb1 /home ext4 defaults 0 0 >> /etc/fstab

At this point, all Settings are complete.
