#### 概述

由于`fdisk`命令最多只支持2TB磁盘分区，并不支持更大的磁盘，需要使用GPT格式进行分区。

```shell
[root@localhost ~]# fdisk /dev/sdb -l
Disk /dev/sdb: 10561.8 GB, 10561795743744 bytes, 20628507312 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 262144 bytes / 2883584 bytes

[root@localhost ~]# lsblk
NAME            MAJ:MIN RM   SIZE RO TYPE MOUNTPOINT
sda               8:0    0 447.1G  0 disk

└─sda2            8:2    0 446.6G  0 part

  ├─centos-home 253:2    0   100G  0 lvm  /home
  └─centos-var  253:3    0    80G  0 lvm  /var
sdb               8:16   0   9.6T  0 disk 
sr0              11:0    1  1024M  0 rom
```
