利用gdisk工具进行分区转换
[root@localhost /]# yum install -y gdisk
转换/dev/sda2分区,sda1分区为系统启动分区,不需要转换
[root@localhost /]# gdisk /dev/sda2
GPT fdisk (gdisk) version 0.8.10
Partition table scan:
MBR: not present
BSD: not present
APM: not present
GPT: not present
Creating new GPT entries.
Command (? for help): w
Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!
Do you want to proceed? (Y/N):
输入y,开始
OK; writing new GUID partition table (GPT) to /dev/sda2.
Warning: The kernel is still using the old partition table.
The new table will be used at the next reboot.
The operation has completed successfully.
[root@localhost /]#
查看分区类型
[root@localhost /]# fdisk -l /dev/sda2
WARNING: fdisk GPT support is currently new, and therefore in an experimental phase. Use at your own discretion.
