一、为VMware虚拟机添加硬盘

1. 首先在VMware虚拟机的VM->Setting子菜单中为虚拟机添加一块15G大小的SCSI类型的硬盘（注意：如果原来为IDE硬盘，SCSI类型的硬盘可能添加不成功，则可以添加IDE类型的硬盘）。

2. 下面是为VMware虚拟机添加额外硬盘完整的命令：

[root@localhost GemOcean]# fdisk

Usage: fdisk [-l] [-b SSZ] [-u] device
E.g.: fdisk /dev/hda (for the first IDE disk)
or: fdisk /dev/sdc (for the third SCSI disk)
or: fdisk /dev/eda (for the first PS/2 ESDI drive)
or: fdisk /dev/rd/c0d0 or: fdisk /dev/ida/c0d0 (for RAID devices)
...
[root@localhost GemOcean]# fdisk -l

Disk /dev/sda: 8589 MB, 8589934592 bytes
255 heads, 63 sectors/track, 1044 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x000796ac

Disk /dev/sdb: 16.1 GB, 16106127360 bytes
255 heads, 63 sectors/track, 1958 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x00000000

Disk /dev/sdb doesn't contain a valid partition table
[root@localhost GemOcean]#
[root@localhost GemOcean]#
[root@localhost GemOcean]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xa2a25246.
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 1958.
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)

二、为新添加的硬盘创建Samba共享文件

Samba 使用 /etc/samba/smb.conf 作为它的配置文件。如果你改变了这个配置文件，这个改变直到你使用 service smb restart 命令重启 Samba 守护进程后才会生效。

要在你的 Linux 系统上创建 Samba 共享目录，在 smb.conf 文件中添加以下几行（根据你和你的系统需要修改了该文件之后）：

[opt2]
        path = /opt2
        writeable = yes
        browseable = yes
        guest ok = yes

[root@localhost samba]# service smb restart
