LINUX parted支持T级分区

1、rootabintel # parted help用法：parted 选项:.设备命令参数.选项：-h,-i,-s,-v,helpinteractivescriptversion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。显示此求助信息在必要时，提示用户从不提示用户显示版本对文件系统进行一个简单的检查将文件系统复制到另一个分区 打印通用求助信息，或关于COMMAND的信息、 创建新的磁盘标签（分区表）在MINOR创建类型为“文件系统类型”的文件移动编号为MINOR的分区将编号为MINOR的分区命名为“名称”打印分区表，或者分区退出程序挽救临近“起始点”、“终止

2、点”的遗失的分改变位于编号为MINOR的分区中文件系统的大删除编号为MINOR的分区选择要编辑的设备改变编号为MINOR的分区的标志命令： 检查 MINOR cp FROM-DEVICE FROM-MINOR TO-MINOR help COMMAND mklabel 标签类型 mkfs MINOR文件系统类型 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 name MINOR 名称 print MINOR quit rescue起始点终止点 区 resize M

3、INOR起始点终止点 小 rm MINOR select 设备 set MINOR标志状态大于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#parted /dev/sdcGNU Parted 1.6.19Copyright (C) 1998 - 2004 Free Software Foundation, Inc.This program is free software, covered by the GNU General Public License.Thi
