1、先取消挂载磁盘,安装一个gdisk工具

yum install -y gdisk

2、分区格式转换,以防万一可以先使用云硬盘备份功能对磁盘进行一个备份,毕竟数据的安全才是第一位!!

# 执行以下命令
[root@nginx-web ~]# gdisk /dev/vdc
GPT fdisk (gdisk) version 0.8.10

Partition table scan:
  MBR: MBR only
  BSD: not present
  APM: not present
  GPT: not present

***************************************************************
Found invalid GPT and valid MBR; converting MBR to GPT format
in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by
typing 'q' if you don't want to convert your MBR partitions
to GPT format!
***************************************************************

Command (? for help): w    ###输入 w 保存

Final checks complete. About to write GPT data. THIS WILL OVERWRITE EXISTING
PARTITIONS!!

Do you want to proceed? (Y/N): y  ## 输入y,将新的分区表写入/dev/vdc磁盘
OK; writing new GUID partition table (GPT) to /dev/vdc.
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.

使用fdisk -l 查看,当前磁盘格式就变为了gpt
