需注意以下几点： linux只能扩展磁盘容量而不能减小， 所填写的容量为总容量，即包含已分区的磁盘， 扩展容量时不能有快照哟，大家可以先把快照删除掉。  
2.启动Linux，查看系统分区，并创建分区sda3，命令如下：红色字体命令，\#后为注释：  
\[root@localhost~\]\#fdisk -l  
Disk /dev/sda:32.2GB,32212254720 bytes  
255heads,63sectors/track,3916cylinders  
Units=cylindersof16065\*512=8225280 bytes

u change display/entry units  
v verify the partition table  
w write table to disk and exit
