sda 8:0 0 100G 0 disk
sdb 8:16 0 5G 0 disk
sr0 11:0 1 1024M 0 rom
Step 02: Create Partition
[root@SysAdmin ~]# fdisk
/dev/sdb
Welcome to fdisk (util-linux 2.37.4).
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 0x71729618.
Command (m for help): p

Created a new partition 1 of type 'Linux' and of size 2
GiB.
Partition #1 contains a xfs signature.
Do you want to remove the signature? [Y]es/[N]o: Y
The signature will be removed by a write command.

Command (m for help): w
The partition table has been altered.
Calling ioctl() to re-read partition table.
Syncing disks.
Step 03: Change type of partition
[root@SysAdmin ~]# fdisk
