在虚拟机中模拟为CentOS系统添加硬盘
在虚拟机中模拟为CentOS系统添加硬盘
操作环境:VMware+CentOS5.0
实验目的:为CentOS5.0系统添加一块新磁盘,并mount到md目录下
实验过程:
步骤1:从VMare虚拟添加一块8G的磁盘
菜单中选择VM-->Settings,出现如下对话框(也可双击device界面)
按照提示做如下操作:选择Add---> Hard Disk--->Create a new virtual disk---->next---->select a type(scsi)--->capity--->ok
第二步:启动虚拟机,在Unix系统中添加磁盘,并划分为一个分区

- The number of cylinders for this disk is set to 1044.
- 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)
