一、实验环境

VMware虚拟机 CentOS 7

二、需求分析

Linux系统一般是作为服务器的，分区采用LVM分区，之前LVM分区采用2TB的分区大小，现在硬盘越来越大，超过2TB的很常见。对于超过2TB的话，需要采用parted分区模式。

三、实验步骤

先在虚拟机中加一块大小为4096GB的硬盘，即为4TB 查看分区，分区为sdd

[root@localhost ~]# fdisk -l //查看一下分区信息 ...... 磁盘 /dev/sdd：4398.0 GB, 4398046511104 字节，8589934592 个扇区 Units = 扇区 of 1 * 512 = 512 bytes 扇区大小(逻辑/物理)：512 字节 / 512 字节 I/O 大小(最小/最佳)：512 字节 / 512 字节

进入/dev/sdd 使用help命令，相当于MBR中的m，帮助指令

[root@localhost ~]# parted /dev/sdd GNU Parted 3.1 使用 /dev/sdd 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 help [COMMAND] print general help, or help on COMMAND mklabel,mktable LABEL-TYPE create a new disklabel (partition table) mkpart PART-TYPE [FS-TYPE] START END make a partition name NUMBER NAME name partition NUMBER as NAME print [devices|free|list,all|NUMBER] display the partition table, available devices, free space, all found partitions, or a particular partition quit exit program rescue START END rescue a lost partition near START and END resizepart NUMBER END resize partition NUMBER rm NUMBER delete partition NUMBER select DEVICE choose the device to edit disk_set FLAG STATE change the FLAG on selected device disk_toggle [FLAG] toggle the state of FLAG on selected device set NUMBER FLAG STATE change the FLAG on partition NUMBER toggle [NUMBER [FLAG]] toggle the state of FLAG on partition NUMBER unit UNIT set the default unit to UNIT version display the version number and copyright information of GNU Parted

创建新的分区表，一般用gpt类型 创建新分区大小：起始容量0T、结束容量1T，大小为1T

(parted) mklabel gpt (parted) mkpart primary 0 1T 警告: The resulting partition is not properly aligned for best performance. 忽略/Ignore/放弃/Cancel? 忽略/Ignore/放弃/Cancel? ignore

再创建一个大小为2T的分区 p命令显示分区信息

(parted) mkpart primary 1T 3T (parted) p Model: VMware, VMware Virtual S (scsi) Disk /dev/sdd: 4398GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name 标志 1 17.4kB 1000GB 1000GB primary 2 1000GB 3000GB 2000GB primary

使用rm命令可以删除分区

(parted) rm 分区编号？ 2 (parted) p Model: VMware, VMware Virtual S (scsi) Disk /dev/sdd: 4398GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name 标志 1 17.4kB 1000GB 1000GB primary

quit命令为退出

(parted) quit 信息: You may need to update /etc/fstab.

parted分区完后，就可以用fdisk命令进行划分了
