分區模式中的王思聰：GPT
傳統分區模式MBR
主分區最多4個
單個分區容量不能大於2TB
沒有主分區系統將無法引導
GPT分區模式
主分區最多128個
單個分區容量不能大於18EB
不存在主分區邏輯分區的概念
不適合安裝X86架構的系統
GPT分區創建方法：parted命令
[root@tomshen ~]# parted GNU Parted 2.1 #版本 使用 /dev/sda #默認指定第一塊磁盤 Welcome to GNU Parted! Type 'help' to view a list of commands. (parted)
parted命令：獲取幫助信息
help 或h

parted命令:創建分區(交互式)
使用mkpart命令不帶參數交互式創建分區
如在/dev/sdb上創建分區，首先使用select命令切換到/dev/sdb
(parted) select /dev/sdb #切換到/dev/sdb 使用 /dev/sdb (parted) mklabel gpt #使用mklabel命令指定分區表類型默認爲msdos(既MBR) 警告: The existing disk label on /dev/sdb will be destroyed and all data on this disk will be lost. Do you want to continue? 是/Yes/否/No? y (parted) (parted) mkpart #開始創建 分區名稱？ []? mygpt #輸入分區名稱(卷標) 文件系統類型？ [ext2]? ext4 #輸入文件系統類型（默認ext2） 起始點？ 4000 #從第幾MB開始 結束點？ 6000 #第幾MB結束 (parted)
使用parted命令創建GPT分區分區範圍是以#MB至#MB表示範圍，而不是#扇區至#扇區。
parted命令:創建分區(命令行式)
語法：mkpart 分區名稱 開始MB 結束MB
(parted) mkpart tomshen 6000MB 8000MB #創建分區tomshen 範圍從6000MB（不包含6000MB）到8000MB (parted) print Model: VMware, VMware Virtual S (scsi) Disk /dev/sdb: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name 標誌 2 3000MB 4000MB 1000MB tom #以前創建的分區 1 4000MB 6000MB 2000MB mygpt 3 6000MB 8000MB 2000MB tomshen (parted)
parted命令:刪除分區
rm 分區編號
(parted) rm 3 (parted) print Model: VMware, VMware Virtual S (scsi) Disk /dev/sdb: 10.7GB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name 標誌 #Number 既分區編號 2 3000MB 4000MB 1000MB tom 1 4000MB 6000MB 2000MB mygpt (parted)
退出parted命令行：quit
如果要退出parted命令行的話，輸入quit即可。
