# parted /dev/sdb
GNU Parted 1.8.1
Using /dev/sdb
Welcome to GNU Parted! Type ‘help’ to view a list of commands.

(parted) mklabel gpt
将MBR磁盘格式化为GPT

(parted) mkpart primary 0 100

划分一个起始位置为0大小为100M的主分区

###不写单位默认是Mb，可以写单位，M G T

(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

划分所有空间到一个分区

(parted) print
打印当前分区

(parted) quit

可能还会用到的一些命令

(parted) mklable msdos
如果要反过来.将GPT磁盘转化为MBR磁盘

在这样分完分区后,还要使用mkfs.ext3来进行格式化
#partprobe
#mkfs.ext3 -F /dev/sdb1

记的哦，因为fdisk是不支持GPT磁盘，所以使用fdisk -l来查看X磁盘刚才的分区是没有用的.

命令行的模式：

将硬盘转化为GPT磁盘后，执行下列命令

parted /dev/sdx mkpart primary 0 100 ##划分一个起始位置为0大小为100M的主分区

=======================================================================================================

[root@abintel ~]# parted --help
用法：parted [选项]... [设备 [命令 [参数]...]...]
将带有“参数”的命令应用于“设备”。如果没有给出“命令”，则以交互模式运行。

选项：
-h, --help                    显示此求助信息
-i, --interactive             在必要时，提示用户
-s, --script                  从不提示用户
-v, --version                 显示版本

命令：
检查 MINOR                   对文件系统进行一个简单的检查
cp [FROM-DEVICE] FROM-MINOR TO-MINOR      将文件系统复制到另一个分区
help [COMMAND]                打印通用求助信息，或关于 COMMAND 的信息
mklabel 标签类型              创建新的磁盘标签 (分区表)
mkfs MINOR 文件系统类型       在 MINOR 创建类型为“文件系统类型”的文件系统
mkpart 分区类型 [文件系统类型] 起始点终止点      创建一个分区
mkpartfs 分区类型文件系统类型起始点终止点创建一个带有文件系统的分区
move MINOR 起始点终止点      移动编号为 MINOR 的分区
name MINOR 名称               将编号为 MINOR 的分区命名为“名称”
print [MINOR]                 打印分区表，或者分区
quit                          退出程序
rescue 起始点终止点          挽救临近“起始点”、“终止点”的遗失的分区
resize MINOR 起始点终止点    改变位于编号为 MINOR 的分区中文件系统的大小
rm MINOR                      删除编号为 MINOR 的分区
select 设备                 选择要编辑的设备
set MINOR 标志状态           改变编号为 MINOR 的分区的标志

大于1T的磁盘进行分区
遇到一个问题,大磁盘的超过1T的时候fdisk无法分区,到网上找了半天才知道是用parted可以作,有网络真好啊.:D

linux支持2T以上大硬盘分区的安装手记
http://bbs.njcit.edu.cn/thread-9091-1-1.html

背景：构建图书馆光盘管理系统FTP，6块硬盘，每个1TB，用一块硬盘做raid0,安装系统，剩余5块做raid5。由于ext3文件系统不支持大于 2TB的分区，所以考虑使用GPT首先以root身份登录系统，查看硬盘信息：fdisk -l

搞定.
因为fdisk是不支持GPT磁盘，所以不要使用fdisk -l来查看X磁盘刚才分好的区，看不到的
