The following steps are described below:  1. Divided into two primary partitions (Create Disk label mklable, then partition Mkpart partition type) [[email protected] ~]# Parted/dev/sdb # Use Parted to operate on GPT disks, enter interactive mode GNU Parted 1.8.1 using/dev/sdb Welcome to GNU parted! Type ' help ' to view a list of commands.

Then format to EXT4, you need to install package e4fsprogs.x86_64 (yum install e4fsprogs.x86_64). [[email protected] ~]# mkfs.ext4/dev/sdb1[[email protected] ~]# mkfs.ext4/dev/sdb2 3.
