继续创建逻辑分区

更改磁盘分区表类型
mkabel gpt
我们从上文知道，sdb硬盘是mbr分区类型的，这里我们就改为gbt分区类型。
这条命令很危险，只能对新的硬盘操作！！
1 2 3 4
(parted) mklabel gpt 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
查询分区表4
1 2 3 4 5 6 7 8 9 10

(parted)
我们看到，分区类型成功改为gpt
创建主分区
gpt分区类型是没有拓展分区的！
1 2 3 4 5 6 7 8 9 10 11 12 13 14

输入q退出，并查询分区情况
1 2 3 4 5
(parted) q 信息: You may need to update /etc/fstab.
[root@localhost ~]# ls /dev/sdb* /dev/sdb /dev/sdb1 /dev/sdb2
我们可以看见，以及成功分出两个分区
使用fdisk查询看看
fdisk -l
这里截取部分信息
