第二步：按mbr格式分区。分两个主分区,大小分别为2G和3G

[root@lzw ~]# lsblk

sda       8:0    0    5G  0 disk 
sr0      11:0    1   11G  0 rom  /run/media/root/RHEL-9-5-0-BaseOS-x86_64
nvme0n1 259:0    0   20G  0 disk 
├─nvme0n1p1
│       259:1    0  600M  0 part /boot/efi
├─nvme0n1p2
│       259:2    0    1G  0 part /boot
└─nvme0n1p3
        259:3    0 18.4G  0 part 
  ├─rhel-root
  │     253:0    0 16.4G  0 lvm  /
  └─rhel-swap

[root@lzw ~]# fdisk /dev/sda

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 0xfee181b3.

Command (m for help): n
Partition type
   p   primary (0 primary, 0 extended, 4 free)
   e   extended (container for logical partitions)
Select (default p): 

Using default response p.
Partition number (1-4, default 1): 
First sector (2048-10485759, default 2048): 
Last sector, +/-sectors or +/-size{K,M,G,T,P} (2048-10485759, default 10485759): +2g

nvme0n2       259:4    0   15G  0 disk 
[root@lzw ~]# parted /dev/nvme0n2
GNU Parted 3.5
Using /dev/nvme0n2
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt                                                      
(parted) mkpart primary 0 5GB

第二步:主分区创建xfs类型的文件系统，挂载到/guazai5目录，在其中存入5.txt的文件，其文件内容是this is 5.txt。

[root@lzw ~]# mkfs.xfs /dev/nvme0n2
mkfs.xfs: /dev/nvme0n2 appears to contain a partition table (gpt).
mkfs.xfs: Use the -f option to force overwrite.
[root@lzw ~]# mkdir /guazai5
[root@lzw ~]# mount /dev/nvme0n2/guazai6
mount: /dev/nvme0n2/guazai5: can't find in /etc/fstab.
[root@lzw ~]# mount /dev/nvme0n2 /guazai5
