在 Google Cloud Compute Engine 上调整 Linux 持久磁盘（MBR 分区）的大小

我想扩展我的 Google Cloud 机器的磁盘容量，并一直在遵循位于的教程这里。

但是，我相当确定本教程假设用户有 GPT 分区表，但我有 MBR。我只需要 20GB，所以这应该不是问题。

无论如何，我按照教程进行到步骤 4a，一切似乎都执行得很好，包括与命令相关的所有内容sudo parted /dev/sda。

但是，当我到达步骤 4b 并提示您运行时sudo sgdisk --move-second-header /dev/sda，我收到以下消息：

Warning: Partition table header claims that the size of partition table

entries is 1119092736 bytes, but this program supports only 128-byte entries.

Adjusting accordingly, but partition table may be garbage.

Warning: Partition table header claims that the size of partition table

entries is 0 bytes, but this program supports only 128-byte entries.

Adjusting accordingly, but partition table may be garbage.


***************************************************************

Found invalid GPT and valid MBR; converting MBR to GPT format

in memory.

***************************************************************



Warning! Secondary partition table overlaps the last partition by

33 blocks!

You will need to delete this partition or resize it in another utility.

Non-GPT disk; not saving changes. Use -g to override.

我不知道下一步该做什么。目前，我有 20GB 可用，但我的 sda1 显示只有 10GB。

如果有帮助的话，这里是输出sudo df -Th：

Filesystem     Type      Size  Used Avail Use% Mounted on

tmpfs          tmpfs     199M  4.0K  199M   1% /run/user/1000

输出如下sudo lsblk：

loop1    7:1    0   115M  1 loop /snap/core/13886

loop6    7:6    0  63.2M  1 loop /snap/core20/1623
sda      8:0    0    20G  0 disk 
└─sda1   8:1    0    20G  0 part /

答案1

运行该命令sudo resize2fs /dev/sda1并跳过sudo sgdisk --move-second-header /dev/sda，因为剩余空间已被识别lsblk
