linux parted命令
2013-02-05parted是一个磁盘分区管理管理工具,它比fdisk更加灵活，fdisk不支持GPT功能也更丰富，同时还支持GPT磁盘(GUID Partition Table)。parted同时支持交互模式和非交互模式. 它除了能够进行分区的添加,删除等常见操作外,还可以移动分区, 制作文件系统, 调整文件系统大小, 复制文件系统.
====== 1. 交互式模式 ======
由于MBR分区表只支持2T磁盘，所以大于2T的磁盘必须使用GPT分区表，具体方法如下：
GPT格式的磁盘相当于原来MBR磁盘中原来保留4个partition table的4*16个字节,只留第一个16个字节，类似于扩展分区，真正的partition table在512字节之后，GPT磁盘没有四个主分区的限制。
在提示符下输入parted就会进入交互式模式,如果有多个磁盘的话，我们需要运行select sdx x为磁盘，来进行磁盘的选择
代码
parted>
parted>select sdb //假设磁盘为sdb
parted>mklabel gpt //将MBR磁盘格式化为GPT GPT分区表：（GPT含义：GUID分区表）
#parted>mklabel msdos //将GPT磁盘转化为MBR磁盘
parted>mkpart primary 0 100 //划分一个起始位置为0，大小为100M的主分区
parted>mkpart primary 100 200 //划分一个起始位置为100M，大小为100M的主分区
#parted>mkpart primary 0 -1 //将整块磁盘分成一个分区
parted>print //打印当前分区
parted>quit //退出
[root@server01 ~]# parted
