一.添加一块新的磁盘设备
1>.将虚拟机关机，点击"编辑虚拟机设置"
2>.点击"添加"按钮
3>.选择添加虚拟硬件的类型为"硬盘"并点击下一步
4>.点击下一步
5>.点击下一步
6>.点击"将虚拟磁盘存储为单个文件"并点击下一步
7>.自定义新硬盘的名称
8>.点击保存按钮
9>.启动虚拟机
二.分区并创建文件系统
1>.查看硬盘资源
[root@yinzhengjie ~]# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sr0 11:0 1 3.7G 0 rom sda 8:0 0 500G 0 disk ├─sda1 8:1 0 500M 0 part /boot └─sda2 8:2 0 499.5G 0 part ├─vg_node200-lv_root (dm-0) 253:0 0 50G 0 lvm / ├─vg_node200-lv_swap (dm-1) 253:1 0 3.9G 0 lvm [SWAP] └─vg_node200-lv_home (dm-2) 253:2 0 445.7G 0 lvm /home sdb 8:16 0 20G 0 disk [root@yinzhengjie ~]#
2>.使用fdisk命令对sdb硬盘进行分区操作

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite) WARNING: DOS-compatible mode is deprecated. It's strongly recommended to switch off the mode (command 'c') and change display units to sectors (command 'u').
