linux下線上擴大擴充套件分割槽的方法

下面是我在linux下擴大檔案系統的的詳細步驟，說明懶得寫了，以後有時間再填一下吧，呵呵

[root@kmdb02 cciss]# fdisk c0d0

The number of cylinders for this disk is set to 105398.
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)
