parted

磁盘分区和分区大小调整工具

补充说明

parted命令 是由GNU组织开发的一款功能强大的磁盘分区和分区大小调整工具,与fdisk不同,它支持调整分区的大小。作为一种设计用于Linux的工具,它没有构建成处理与fdisk关联的多种分区类型,但是,它可以处理最常见的分区格式,包括:ext2、ext3、fat16、fat32、NTFS、ReiserFS、JFS、XFS、UFS、HFS以及Linux交换分区。

语法

1parted(选项)(参数)

选项

1-h:显示帮助信息;
2-i:交互式模式;
3-s:脚本模式,不提示用户;
4-v:显示版本号。

参数

  • 设备:指定要分区的硬盘所对应的设备文件;
  • 命令:要执行的parted命令。

实例

从串行技术出现以来,越来越多用户选择使用大容量的SATA硬盘创建磁盘阵列;特别是MD1000/MD3000,很轻易就突破2T的LUN,故在此给大家一些指引。

红帽企业 Linux 4 Update 4供对大于 2 terabytes(TB)的磁盘设备的支持。

请参考以下操作步骤:

注:

  • 绿色代表你需要使用的命令。
  • 红色代表你需要注意到的输出信息,在后续需要使用。
