使用parted给大于2T的磁盘分区

1.使用命令parted /dev/sdb

 [root@server ~]# parted /dev/sdb
 GNU Parted 2.1
 使用 /dev/sdb
 Welcome to GNU Parted! Type 'help' to view a list of commands.
                                                                      (parted) help
   align-check TYPE N                        check partition N for
         TYPE(min|opt) alignment
   check NUMBER                             do a simple check on the
         file system
   cp [FROM-DEVICE] FROM-NUMBER TO-NUMBER   copy file system to
         another partition
   help [COMMAND]                           print general help, or
         help on COMMAND

2.修改gpt分区表

 (parted) p
 Model: VMware, VMware Virtual S (scsi)
 Disk /dev/sdb: 1074MB
 Sector size (logical/physical): 512B/512B
 Partition Table: msdos
 
 Number  Start  End  Size  Type  File system  标志
 
 (parted) mklabel gpt   //使用mklabel修改为gpt分区
 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? yes
 (parted) p
 Model: VMware, VMware Virtual S (scsi)
 Disk /dev/sdb: 1074MB
 Sector size (logical/physical): 512B/512B
 Partition Table: gpt

3.创建分区说明

mkpart PART-TYPE [FS-TYPE] START END make a partition
mkpartfs PART-TYPE FS-TYPE START END make a partition with a

4.创建主分区为200M的分区

 (parted) mkpart primary 0 200    //使用命令mkpart
 警告: The resulting partition is not properly aligned for best
 performance.
 忽略/Ignore/放弃/Cancel? I
 (parted) p
 Model: VMware, VMware Virtual S (scsi)
 Disk /dev/sdb: 1074MB
 Sector size (logical/physical): 512B/512B
 Partition Table: gpt
 
 Number  Start   End    Size   File system  Name     标志
  1      17.4kB  200MB  200MB               primary

5.创建主分区为100M的分区

 (parted) mkpart primary 200 300       //mkpart 主分区  start  end
 (parted) p
 Model: VMware, VMware Virtual S (scsi)
 Disk /dev/sdb: 1074MB
 Sector size (logical/physical): 512B/512B
 Partition Table: gpt
 
 Number  Start   End    Size    File system  Name     标志
  1      17.4kB  200MB  200MB                primary
  2      200MB   300MB  99.6MB               primary

6.创建一个逻辑分区并且指定文件类型ext4

 (parted) mkpart logical ext4 301 400 ignore
   align-check TYPE N                        check partition N for
         TYPE(min|opt) alignment
   check NUMBER                             do a simple check on the
         file system
   cp [FROM-DEVICE] FROM-NUMBER TO-NUMBER   copy file system to
         another partition
   help [COMMAND]                           print general help, or

 (parted) p
 Model: VMware, VMware Virtual S (scsi)
 Disk /dev/sdb: 1074MB
 Sector size (logical/physical): 512B/512B
 Partition Table: gpt
 
 Number  Start   End    Size    File system  Name     标志
  1      17.4kB  200MB  200MB                primary
  2      200MB   300MB  99.6MB               primary
  3      301MB   400MB  98.6MB               logical

7.直接在命令行下分区

 [root@server ~]# parted /dev/sdb mklabel gpt yes
 [root@server ~]# parted /dev/sdb mkpart primary ext4 0 10 ignore
 [root@server ~]# parted /dev/sdb mkpart primary linux-swap 11 20 ignore
 [root@server ~]# parted /dev/sdb mkpart logical ext4 21 30 ignore
 [root@server ~]# parted /dev/sdb p

8.扩展

对新添加的磁盘快速分区方法：

#echo -e "n\np\n1\n\n+10G\nn\np\n2\n\n+20G\nw" |fdisk /dev/sdb

#partprobe
