首先分区：

# fdisk /dev/sda

The number of cylinders for this disk is set to 60801.

There is nothing wrong with that, but this is larger than 1024,
- r$ K( z3 X+ C x# |: _+ N
and could in certain setups cause problems with:

1) software that runs at boot time (e.g., old versions of LILO)
6 c' _5 [6 N3 o
2) booting and partitioning software from other OSs

执行下面的命令不必重启机器：

创建物理卷：

创建卷组：
