虚拟机测试

在vmware添加一块新的硬盘，一路默认就可以

 

新添加的硬盘使用lsblk查看的时候是显示不了的。需要刷新硬盘

echo '- - -' > /sys/class/scsi_host/host2/scan

如果执行命令之后还是不显示，就将host2更换成host0，再次查看应该就会有的。

 

sdb就是新硬盘

接下来是分区

创建挂载点并挂载

[root@centos7 ~]# mkdir /mnt/sdb1
[root@centos7 ~]# mount /dev/sdb1 /mnt/sdb1/

将sdb1写入文件，以达到永久挂载，开机自动挂载

[root@centos7 ~]# vim /etc/fstab
