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)(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:
