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 (2048-1953525167, default 1953525167): Created a new partition 1 of type 'Linux' and of size 931.5 GiB. Command (m for help): w The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks.

4 change the file format of the new partition to ext4

linlf@dacent:~$ sudo mkfs.ext4 /dev/sdb1 mke2fs 1.42.13 (17-May-2015) Creating filesystem with 244190390 4k blocks and 61054976 inodes Filesystem UUID: 938e6783-d5cb-4e38-98e2-e8e2b0918587 Superblock backups stored on blocks: 32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208, 4096000, 7962624, 11239424, 20480000, 23887872, 71663616, 78675968, 102400000, 214990848 Allocating group tables: done Writing inode tables: done Creating journal (32768 blocks): done Writing superblocks and filesystem accounting information: done

5 view the file type and device number of the new partition

linlf@dacent:~$ sudo blkid /dev/sdb1 /dev/sdb1: UUID="928e6783-d5cb-4e38-98e2-e8e2b0918587" TYPE="ext4" PARTUUID="6219375b-01"

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
