操作环境
Centos 7
操作步骤
最近在linux测试机上面，通过fdisk 查看硬盘，发现几块1TB的硬盘都变成了GPT分区，无法通过fdisk进行分区操作，所以要通过parted 删除其GPT分区

1.选择sdc进行删除GPT分区操作
[root@docker-server-1 ~]# parted /dev/sdc GNU Parted 2.1 Using /dev/sdc Welcome to GNU Parted! Type 'help' to view a list of commands. (parted)
2.通过mklabel建立msdos分区
(parted) mklabel New disk label type? msdos Warning: The existing disk label on /dev/sdc will be destroyed and all data on this disk will be lost. Do you want to continue? Yes/No? Yes Warning: /dev/sdc contains GPT signatures,indicating that it has a GPT table. However,it does not have a valid fake msdos partition table,as it should. Perhaps it was corrupted -- possibly by a program that doesn't understand GPT partition tables. Or perhaps you deleted the GPT table,and are now using an msdos partition table. Is this a GPT partition table? Yes/No? Yes3.再次通过fdisk 查看sdc，就不会提示GPT分区了
