Ubuntu mounts a new hard disk

2 create a new partition for the sdb hard disk

linlf@dacent:~$ sudo fdisk /dev/sdb 

Welcome to fdisk (util-linux 2.27.1).
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 0x6d19375b.

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): 

Using default response p.
Partition number (1-4, default 1): 
First sector (2048-1953525167, default 2048): 
Last sector, +sectors or +size{K,M,G,T,P} (2048-1953525167, default 1953525167): 

Created a new partition 1 of type 'Linux' and of size 931.5 GiB.

4 change the file format of the new partition to ext4

linlf@dacent:~$ sudo mkfs.ext4 /dev/sdb1

linlf@dacent:~$ sudo blkid /dev/sdb1

6. After we have a new partition, we can start to mount it. Because I want to use more storage space, I mount it in the / home directory. Please note that the same directory cannot be mounted in different partitions.

dacent@dacent:~$ sudo mkdir /new
dacent@dacent:~$ sudo mount /dev/sdb1 /new
dacent@dacent:~$ sudo cp -r /home/* /new
dacent@dacent:~$ 
dacent@dacent:~$ ls /new/  (Check whether the copy is successful)
dacent	linlf
dacent@dacent:~$ sudo umount /dev/sdb1
dacent@dacent:~$ sudo mount /dev/sdb1 /home (Successfully attached)

7 finally, to make the new hard disk boot and mount automatically, add a line sudo vi /etc/fstab in / etc/fstab

UUID=928e6783-d5cb-4e38-98e2-e8e2b0918587   /home   ext4    defaults    0   2

8 restart to verify the last step.

reboot
