linux parted指令,parted指令詳解

[[email protected] ~]# parted --help

用法:parted [選項]... [裝置 [指令 [參數]...]...]

将帶有“參數”的指令應用于“裝置”。如果沒有給出“指令”,則以互動模式運作。

選項:

-h, --help                    顯示此求助資訊

-i, --interactive             在必要時,提示使用者

-s, --script                  從不提示使用者

-v, --version                 顯示版本

指令:

檢查 MINOR                   對檔案系統進行一個簡單的檢查

cp [FROM-DEVICE] FROM-MINOR TO-MINOR      将檔案系統複制到另一個分區

help [COMMAND]                列印通用求助資訊,或關于 COMMAND 的資訊

mklabel 标簽類型              建立新的磁盤标簽 (分區表)

mkfs MINOR 檔案系統類型       在 MINOR 建立類型為“檔案系統類型”的檔案系統

mkpart 分區類型 [檔案系統類型] 起始點 終止點      建立一個分區

mkpartfs 分區類型 檔案系統類型 起始點 終止點 建立一個帶有檔案系統的分區

move MINOR 起始點 終止點      移動編号為 MINOR 的分區

name MINOR 名稱               将編号為 MINOR 的分區命名為“名稱”

print [MINOR]                 列印分區表,或者分區

quit                          退出程式

rescue 起始點 終止點          挽救臨近“起始點”、“終止點”的遺失的分區

resize MINOR 起始點 終止點    改變位于編号為 MINOR 的分區中檔案系統的大小

rm MINOR                      删除編号為 MINOR 的分區

select 裝置                 選擇要編輯的裝置

set MINOR 标志 狀态           改變編号為 MINOR 的分區的标志

大于1T的磁盤進行分區

遇到一個問題,大磁盤的超過1T的時候fdisk無法分區,到網上找了半天才知道是用parted可以作,有網絡真好啊.:D

下面一塊有3T RAID的硬碟的分區情況

linux支援2T以上大硬碟分區的安裝手記

背景:建構圖書館CD光牒管理系統FTP,6塊硬碟,每個1TB,用一塊硬碟做raid0,安裝系統,剩餘5塊做raid5。由于ext3檔案系統不支援大于 2TB的分區,是以考慮使用GPT首先以root身份登入系統,檢視硬碟資訊:fdisk -l

因為fdisk是不支援GPT磁盤,是以不要使用fdisk -l來檢視X磁盤剛才分好的區,看不到的
