Steps:
1) Check to see how many drives are installed:
Use the fdisk command to verify how many drives are mounted.
[root@linux]# fdisk -l | grep '^Disk'
The output should be similar to the following:
Disk /dev/sda: 500.1 GB, 500107862016 bytes
Disk /dev/sdb: 500.1 GB, 500107862016 bytes
2) To partition the disk - /dev/sdb, enter:
[root@linux root]# fdisk /dev/sdb
For help option and switches, use the “m” command:
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
partitions using the command “p”:
Device Boot Start End Blocks Id System
/dev/sda1 * 2048 968615935 484306944 83 Linux
/dev/sda2 968617982 976771071 4076545 5 Extended
/dev/sda5 968617984 976771071 4076544 82 Linux swap / Solaris
3) To create a new partition, issue the command “n” and then select “p” for primary and 1-4 depending on which partition on the drive this is (first, second, third, or fourth):
n(creates a new partition)
p(creates a primary partition)
1(the number 1 denotes the partition will be /dev/sdb1)
Command (m for help):
e extended
p primary partition (1-4)
Partition number (1-4): 1
First cylinder (1-6081, default 1): 1
Last cylinder or +size or +sizeM or +sizeK (1-6081, default 6081): 6081
To save the partition, use the “w” command:
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
[root@default root]#
4) Format the new disk using mkfs.ext4 command:
To format Linux partions using ext3fs on the new disk, issue the following command:
[root@default]#mkfs.ext4 /dev/sdb1
5) Mount the new disk using the mount command:
First, you'll need to create a mount point. We'll use /disk1. This is where we'll mount /dev/sdb1. Enter the following commands:
[root@default]# mkdir /disk1
[root@default]# mount /dev/sdb1 /disk1
[root@default]# df -H
6) Edit /etc/fstab so the new drive will automatically mount to /disk1 on reboot
