[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
下面一块有3T RAID的硬盘的分区情况

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

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
