vmware下linux 如何添加硬盘

1.在虚拟机的设置中增加一块硬盘。

  setting -> add disk -> create a new virtual disk -> SCSI

  设定大小，这里给3G；更改名称，我这个硬盘用来安装Oracle ,名字为oradata.vmdk

2.格式化硬盘。 

[root@libydwei ~]# fdisk -l /dev/sdb

Disk /dev/sdb: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Disk /dev/sdb doesn't contain a valid partition table

  对硬盘进行格式化，这里不用指定分区类型，默认的linux就可以。

[root@libydwei ~]# fdisk /dev/sdb

Command (m for help): p

Disk /dev/sdb: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot Start End Blocks Id System

Command (m for help): n

   e extended
   p primary partition (1-4)
p
Partition number (1-4): q
Partition number (1-4): 1
First cylinder (1-261, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-261, default 261):
Using default value 261

Command (m for help): p

Disk /dev/sdb: 2147 MB, 2147483648 bytes
255 heads, 63 sectors/track, 261 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot Start End Blocks Id System
/dev/sdb1 1 261 2096451 83 Linux

Command (m for help):

3.创建文件系统

[root@libydwei ~]# mkfs.ext3 /dev/sdb1
4.挂载分区。这里我们要将oracle 挂载在 /u01目录下。

[root@libydwei ~]# mount -t ext3 /dev/sdb1 /u01
[root@libydwei ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda2 3.9G 2.4G 1.3G 66% /
/dev/sda1 46M 11M 33M 24% /boot
none 252M 0 252M 0% /dev/shm
/dev/sda3 7.0G 49M 6.6G 1% /home
/dev/sdb1 2.0G 36M 1.9G 2% /u01
[root@libydwei ~]#

我们看到，这里已经将/dev/sdb1 挂载到了/u01目录。

这样重启以后，还要重新挂载目录。我们写在配置文件中，下次重启自动进行挂载。

在文件末尾添加     /dev/sdb1 /u01 ext3 defaults 0 0
