使用parted给大于2T的磁盘分区

1.使用命令parted /dev/sdb

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

2.修改gpt分区表

1 (parted) p                                                                
 2 Model: VMware, VMware Virtual S (scsi)
 3 Disk /dev/sdb: 1074MB
 4 Sector size (logical/physical): 512B/512B
 5 Partition Table: msdos
 6 
 7 Number  Start  End  Size  Type  File system  标志
 8 
 9 (parted) mklabel gpt   //使用mklabel修改为gpt分区
10 警告: The existing disk label on /dev/sdb will be destroyed and all       
11 data on this disk will be lost. Do you want to continue?
12 是/Yes/否/No? yes                                                         
13 (parted) p                                                                
14 Model: VMware, VMware Virtual S (scsi)
15 Disk /dev/sdb: 1074MB
16 Sector size (logical/physical): 512B/512B
17 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

1 (parted) mkpart primary 0 200    //使用命令mkpart
 2 警告: The resulting partition is not properly aligned for best            
 3 performance.
 4 忽略/Ignore/放弃/Cancel? I                                                
 5 (parted) p
 6 Model: VMware, VMware Virtual S (scsi)
 7 Disk /dev/sdb: 1074MB
 8 Sector size (logical/physical): 512B/512B
 9 Partition Table: gpt
10 
11 Number  Start   End    Size   File system  Name     标志
12  1      17.4kB  200MB  200MB               primary

5.创建主分区为100M的分区

1 (parted) mkpart primary 200 300       //mkpart 主分区  start  end
 2 (parted) p                                                                
 3 Model: VMware, VMware Virtual S (scsi)
 4 Disk /dev/sdb: 1074MB
 5 Sector size (logical/physical): 512B/512B
 6 Partition Table: gpt
 7 
 8 Number  Start   End    Size    File system  Name     标志
 9  1      17.4kB  200MB  200MB                primary
10  2      200MB   300MB  99.6MB               primary

6.创建一个逻辑分区并且指定文件类型ext4

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

1 (parted) p                                                                
 2 Model: VMware, VMware Virtual S (scsi)
 3 Disk /dev/sdb: 1074MB
 4 Sector size (logical/physical): 512B/512B
 5 Partition Table: gpt
 6 
 7 Number  Start   End    Size    File system  Name     标志
 8  1      17.4kB  200MB  200MB                primary
 9  2      200MB   300MB  99.6MB               primary
10  3      301MB   400MB  98.6MB               logical

7.直接在命令行下分区

1 [root@server ~]# parted /dev/sdb mklabel gpt yes
2 [root@server ~]# parted /dev/sdb mkpart primary ext4 0 10 ignore
3 [root@server ~]# parted /dev/sdb mkpart primary linux-swap 11 20 ignore
4 [root@server ~]# parted /dev/sdb mkpart logical ext4 21 30 ignore
5 [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
