Format and mount new hard drive
#1. Figure out the device name for the new device
fdisk -l
#This will give you output similar to this:
#Disk /dev/sda: 17.2 GB, 17179869184 bytes
#255 heads, 63 sectors/track, 2088 cylinders, total 33554432 sectors
#Units = sectors of 1 * 512 = 512 bytes
#Sector size (logical/physical): 512 bytes / 512 bytes
#I/O size (minimum/optimal): 512 bytes / 512 bytes
#Disk identifier: 0x000299d1
#Device Boot Start End Blocks Id System
#/dev/sda1 * 2048 32088063 16043008 83 Linux
#/dev/sda2 32090110 33552383 731137 5 Extended
#/dev/sda5 32090112 33552383 731136 82 Linux swap / Solaris
#Disk /dev/sdb: 17.2 GB, 17179869184 bytes
#255 heads, 63 sectors/track, 2088 cylinders, total 33554432 sectors
#Units = sectors of 1 * 512 = 512 bytes
#Sector size (logical/physical): 512 bytes / 512 bytes
#I/O size (minimum/optimal): 512 bytes / 512 bytes
#Disk identifier: 0x00000000
#Disk /dev/sdb doesn't contain a valid partition table
#2. Next we’ll partion the new disk using the following command:
cfdisk /dev/sdb
#> New -> Primary -> Specify size in MB
#> Write -> yes
#> Quit
#3. Format the new disk using the ext4 filessystem
mkfs.ext4 /dev/sdb1
#4. You need to create a new directory where the disk will be mounted in the filesystem
mkdir /disk2
#5. It’s preferred to use the device UUID (Universally Unique Identifier) instead of directly linking to the device path because while UUID always stays the same, the device path may change. This is how we find the UUID:
blkid
#Which shows a list of all partitions and the assigned UUID. The list should look similar to this:
#/dev/sda5: UUID="180cab2a-300a-4e3d-8c8e-0e1df46b9bf7" TYPE="swap"
#/dev/sda1: UUID="cd0c7b2c-bf50-4557-bc01-0048764a41d2" TYPE="ext4"
#/dev/sdb1: UUID="359d90df-f17a-42f6-ab13-df13bf356de7" TYPE="ext4"
#6. Add the new disk/partition to fstab to automatically mount it on boot
echo "UUID=359d90df-f17a-42f6-ab13-df13bf356de7 /disk2 ext4 errors=remount-ro 0 1" >> /etc/fstab
#Replace the UDID value to the UDID displayed in step 5 for the new disk and replace /disk2 with the path where you want to mount the disk in the filesystem as specified in step 4
#7. Manually mount the disk (you can also reboot the machine and it will be automatically mounted)
mount /disk2
#/disk2 is the directory created in step 4
