VMware安裝Linux的時候默認分配的空間是4GB，可能會不夠，這個時候可以通過增加一塊虛擬硬盤，將/usr或其他內容拷貝過去解決這個問題：
創建虛擬硬盤
1、關閉VM中正在運行的虛擬系統；
2、在虛擬系統名稱上點右鍵－》Virtual Machine Settings；
3、在Hardware頁點“Add”－》Add a hard disk－》Create a new virtual disk－》SCSI(recommended)－》分配空間大小－》OK；
4、可以看見Hardware中出現了一塊新的硬盤Hard Disk 2。
對虛擬硬盤進行分區和格式化（轉載自bixuan）
[root@cncmail data1]# fdisk -l ## 這裡是查看目前系統上有幾塊硬盤
Disk /dev/sda: 36.4 GB, 36401479680 bytes
255 heads, 63 sectors/track, 4425 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sda1 * 1 255 2048256 83 Linux
/dev/sda2 256 1530 10241437+ 83 Linux
/dev/sda3 4296 4425 1044225 82 Linux swap
/dev/sda4 1531 4295 22209862+ f Win95 Ext'd (LBA)
/dev/sda5 1531 2805 10241406 83 Linux
/dev/sda6 2806 4295 11968393+ 83 Linux
Partition table entries are not in disk order
Disk /dev/sdb: 36.7 GB, 36703918080 bytes ## 這裡發現/dev/sdb，容量36.7G，切未被分區
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdc doesn't contain a valid partition table
[root@linux root]# fdisk /dev/sdb ## 接下去就對/dev/sdb分區進行分區
The number of cylinders for this disk is set to 4462.
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)
Command (m for help): m
Command action
a toggle a bootable flag
b edit bsd disklabel
c toggle the dos compatibility flag
d delete a partition
l list known partition types
m print this menu
n add a new partition
o create a new empty DOS partition table
p print the partition table
q quit without saving changes
s create a new empty Sun disklabel
t change a partition's system id
u change display/entry units
v verify the partition table
w write table to disk and exit
x extra functionality (experts only)
Command (m for help): p ## 打印出目前該硬盤下的分區列表
Disk /dev/sdb: 36.7 GB, 36703918080 bytes
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
Command (m for help): n ## 增加一個分區
Command action
e extended
p primary partition (1-4)
## 因為通常選擇主分區，所以這裡打一個p
p
Partition number (1-4): 1 ## 這裡因為是第一個分卻，所以只選擇1，如果是第二個分區，則選擇2,依次類推
First cylinder (1-4462, default 1): ## 新分區起始的磁盤塊數
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-4462, default 4462): 如果要分區10G，這裡可以直接輸入：+10240M，因為這裡要全部使用硬盤空間，則用默認
Using default value 4462
Command (m for help): p
Disk /dev/sdb: 36.7 GB, 36703918080 bytes
255 heads, 63 sectors/track, 4462 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 4462 35840983+ 83 Linux
## 這裡第一個分區已經分好了，接下去得把這個分區寫入硬盤，用w
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
Syncing disks.
下面的工作就是對該硬盤進行格式，我這裡是格式化成ext3
[root@linux root]# mkfs.ext3 /dev/sdb1 (這裡原來的命令是：mke2fs -j /dev/sdb1，試了一下不成 功，改了)
mke2fs 1.32 (09-Nov-2002)
Filesystem label=

Block size=4096 (log=2)
Fragment size=4096 (log=2)

Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done
This filesystem will be automatically checked every 23 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
檢查一下，是否已經格式好
[root@linux root]# fdisk -l

掛載虛擬硬盤
分區分好，也格式化好了，下面就是掛載
我把/dev/sdb1掛載到/data1下
[root@linux root]# mkdir /data1 ## 首先建立掛載的目錄data1
[root@linux root]# mount /dev/sdb1 /data1 ##將sdb1掛載到data1
重啟系統之後，查看是否掛載成功：
[root@linux data1]# df -h
文件系統 容量 已用 可用 已用% 掛載點
/dev/sda1 2.0G 454M 1.4G 25% /
/dev/sda6 12G 53M 11G 1% /bak
/dev/sdb1 34G 33M 32G 1% /data1
none 250M 0 250M 0% /dev/shm
/dev/sda2 9.7G 1.5G 7.7G 17% /usr
/dev/sda5 9.7G 8.6G 559M 95% /var
這裡看到/dev/sda6 12G 53M 11G 1% /bak
說明已經掛載成功了。到根目錄“/”下可以查看到這個掛載好的data1。
