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

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

三
第一步：选择虚拟磁盘类型选择NVME。大小选择15G

第二步：按gpt格式分区。分一个主分区。大小为5G
[root@lzw ~]# lsblk

└─rhel-swap 253:1 0 2G 0 lvm [SWAP]
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
