在做Oracle 备份恢复实验时，发现我的Linux虚拟机空间不足。

以下为增加10G空间的步骤。
一将Linux系统Power Off ,在虚拟机设置中选择 Add-->Hard Disk-->Next ....
二启动Linux，用Root用户进入系统
三为磁盘创建文件系统：mkfs.ext3 /dev/sdb
四挂载
[root@xugj ~]# mkdir /mnt/sdb
[root@xugj ~]# mount /dev/sdb /mnt/sdb
五分区： fdisk /dev/sdb

点击(此处)折叠或打开

[root@xugj ~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklab el
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
The number of cylinders for this disk is set to 1305.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)

六：将“挂载”动作添加到开机执行中
[root@xugj ~]# vi /etc/fstab
添加一行：
/dev/sdb       /mnt/sdb    ext3 defaults 0 1

七：检验
[root@xugj ~]# df -h
