磁盤分區(qū)和分區(qū)大小調(diào)整工具
parted命令 是由GNU組織開發(fā)的一款功能強(qiáng)大的磁盤分區(qū)和分區(qū)大小調(diào)整工具，與fdisk不同，它支持調(diào)整分區(qū)的大小。作為一種設(shè)計(jì)用于Linux的工具，它沒有構(gòu)建成處理與fdisk關(guān)聯(lián)的多種分區(qū)類型，但是，它可以處理最常見的分區(qū)格式，包括：ext2、ext3、fat16、fat32、NTFS、ReiserFS、JFS、XFS、UFS、HFS以及Linux交換分區(qū)。
parted(選項(xiàng))(參數(shù))
-h：顯示幫助信息；
-i：交互式模式；
-s：腳本模式，不提示用戶；
-v：顯示版本號。
從串行技術(shù)出現(xiàn)以來，越來越多用戶選擇使用大容量的SATA硬盤創(chuàng)建磁盤陣列；特別是MD1000/MD3000，很輕易就突破2T的LUN，故在此給大家一些指引。
紅帽企業(yè) Linux 4 Update 4供對大于 2 terabytes（TB）的磁盤設(shè)備的支持。
請參考以下操作步驟：
