二、安装第二硬盘
1. 查看机器情况
[root@Q!XtcaykhuMd62GD ~]# lsblk
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
vda 253:0 0 40G 0 disk
└─vda1 253:1 0 40G 0 part /
vdb 253:16 0 500G 0 disk
2.硬盘分区
使用fdisk分区
[root@Q!XtcaykhuMd62GD ~]# fdisk vdb
Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
fdisk: cannot open vdb: No such file or directory
[root@Q!XtcaykhuMd62GD ~]# fdisk /dev/vdb
