[root@abintel ~]# parted –help

用法：parted [選項(xiàng)]… [設(shè)備 [命令 [參數(shù)]…]…]

將帶有“參數(shù)”的命令應(yīng)用于“設(shè)備”。如果沒有給出“命令”，則以交互模式運(yùn)行。

選項(xiàng)：

-h, –help????????????????????顯示此求助信息

-i, –interactive???????????? 在必要時(shí)，提示用戶

-s, –script??????????????????從不提示用戶

-v, –version???????????????? 顯示版本

命令：

檢查 MINOR?????????????????? 對文件系統(tǒng)進(jìn)行一個(gè)簡單的檢查

cp [FROM-DEVICE] FROM-MINOR TO-MINOR??????將文件系統(tǒng)復(fù)制到另一個(gè)分區(qū)

help [COMMAND]????????????????打印通用求助信息，或關(guān)于 COMMAND 的信息

mklabel 標(biāo)簽類型??????????????創(chuàng)建新的磁盤標(biāo)簽 (分區(qū)表)

mkfs MINOR 文件系統(tǒng)類型?????? 在 MINOR 創(chuàng)建類型為“文件系統(tǒng)類型”的文件系統(tǒng)

mkpart 分區(qū)類型 [文件系統(tǒng)類型] 起始點(diǎn) 終止點(diǎn)??????創(chuàng)建一個(gè)分區(qū)

mkpartfs 分區(qū)類型 文件系統(tǒng)類型 起始點(diǎn) 終止點(diǎn) 創(chuàng)建一個(gè)帶有文件系統(tǒng)的分區(qū)

move MINOR 起始點(diǎn) 終止點(diǎn)??????移動編號為 MINOR 的分區(qū)

name MINOR 名稱?????????????? 將編號為 MINOR 的分區(qū)命名為“名稱”

print [MINOR]???????????????? 打印分區(qū)表，或者分區(qū)

quit??????????????????????????退出程序

rescue 起始點(diǎn) 終止點(diǎn)??????????挽救臨近“起始點(diǎn)”、“終止點(diǎn)”的遺失的分區(qū)

resize MINOR 起始點(diǎn) 終止點(diǎn)????改變位于編號為 MINOR 的分區(qū)中文件系統(tǒng)的大小

rm MINOR??????????????????????刪除編號為 MINOR 的分區(qū)

select 設(shè)備???????????????? 選擇要編輯的設(shè)備

set MINOR 標(biāo)志 狀態(tài)?????????? 改變編號為 MINOR 的分區(qū)的標(biāo)志

大于1T的磁盤進(jìn)行分區(qū)

遇到一個(gè)問題,大磁盤的超過1T的時(shí)候fdisk無法分區(qū),到網(wǎng)上找了半天才知道是用parted可以作,有網(wǎng)絡(luò)真好啊.:D

下面一塊有3T RAID的硬盤的分區(qū)情況

背景：構(gòu)建圖書館光盤管理系統(tǒng)FTP，6塊硬盤，每個(gè)1TB，用一塊硬盤做raid0,安裝系統(tǒng)，剩余5塊做raid5。由于ext3文件系統(tǒng)不支持大于2TB的分區(qū)，所以考慮使用GPT首先以root身份登錄系統(tǒng)，查看硬盤信息：fdisk -l
