我的第二次RHCSA作业
作业内容：在linux中添加三块硬盘
一、第一块硬盘
1.虚拟磁盘类型选择SCSI，大小选择5G。

2.按mbr格式分区。分两个主分区,大小分别为2G和3G。
[root@zyz ~]# lsblk

[root@zyz ~]# 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.

3.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@zyz ~]# mkfs.xfs /dev/nvme0n3
mkfs.xfs: /dev/nvme0n3 appears to contain a partition table (gpt).
mkfs.xfs: Use the -f option to force overwrite.
[root@zyz ~]# mkfs.xfs -f /dev/nvme0n3
meta-data=/dev/nvme0n3 isize=512 agcount=4, agsize=983040 blks
