How to Create a Disk Partitions in Linux.
For using the storage devices more effectively such as hard drives. you need to understand how to structure them before using it in Linux. big storage devices are split into separate portions called partitions.
In this article, we will explain how to partition a storage disk in Linux systems such as CentOS, RHEL, Fedora, Debian and Ubuntu distributions.
# parted -l
From the output of the above command, there are two hard disks attached to the test system, the first is /dev/sda and the second is /dev/sdb.
In this case, we want to partition hard disk /dev/sdb. To manipulate disk partitions, open the hard disk to start working on it, as shown.
# parted /dev/sdb
At the parted prompt, make a partition table by running mklabel msdos or gpt, then enterY/esto accept it.
(parted) mklabel msdos
Important: Make sure to specify the correct device for partition in the command. If you run parted command without a partition device name, it will randomly pick a storage device to modify.
Next, create a new primary partition on the hard disk and print the partition table as show.
(parted) mkpart primary ext4 0 10024MB
(parted) print
To quit, issue the quit command and all changes are automatically saved.
Next, create the file system type on each partition, you can use the mkfs utility (replace ext4 with the file system type you wish to use).
# mkfs.ext4 /dev/sdb1
# mkfs.ext4 /dev/sdb2
Last but not least, to access the storage space on the partitions, you need to mount them by creating the mount points and mount the partitions as follows.
# mkdir -p /mnt/sdb1 # mkdir -p /mnt/sdb2 # mount -t auto /dev/sdb1 /mnt/sdb1 # mount -t auto /dev/sdb2 /mnt/sdb2
To check if the partitions are actually mounted, run the 'df command' to report file system disk space usage.
# df -hT
