我增加了分区的大小(修改大小后EBS Volume
)
调整大小之前我收到以下警告:
GPT fdisk (gdisk) version 1.0.1
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!
***************************************************************
转换为 GPT 似乎造成了一些损害。
分区大小调整似乎成功,我可以挂载和访问文件。
调整大小后,我无法再使用该 EBS 卷启动机器,该卷似乎不是启动卷。
机器在启动时挂起:

我如何恢复该磁盘的启动功能?
答案1
没有找到解决 mbr/gpt 启动数据损坏的方法。
parted
相反,我使用而不是gdisk
(使用快照备份)重新执行了调整大小的过程。
