Linux下用fdisk進行分區的步驟

當你在Linux服務器上裝上全新的硬盤后，你需要用類似 fdisk 這樣的工具進行相應的分區。

當你在Linux服務器上裝上全新的硬盤后，你需要用類似 fdisk 這樣的工具進行相應的分區。
fdisk中相應的提供5種基本操作：
o n – 創建新分區
o d – 刪除一個已有的分區
o p – 打印現有的分區表
o w – 把改動寫入到分區表，也就是保存.
o q – 離開 fdisk
創建新分區
在下面的例子中, 我創建了主分區 /dev/sda1

# fdisk /dev/sda
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel. 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 34893. 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)
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
Command (m for help): p
Disk /dev/sda: 287.0 GB, 287005343744 bytes
255 heads, 63 sectors/track, 34893 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Command (m for help): n

Partition number (1-4): 1
First cylinder (1-34893, default 1):
Using default value 1
Last cylinder or +size or +sizeM or +sizeK (1-34893, default 34893):
Using default value 34893
Command (m for help): w
The partition table has been altered!
Calling ioctl() to re-read partition table.
