阅读AWS 文档后，我尝试运行以下 Growthpart 命令，但我不清楚需要什么。

\n\n

sudo growpart /dev/nvme0n1p1 1\nWARN: unknown label \nfailed [sfd_dump:1] sfdisk --unit=S --dump /dev/nvme0n1p1\nsfdisk: /dev/nvme0n1p1: does not contain a recognized partition table\nFAILED: failed to dump sfdisk info for /dev/nvme0n1p1\n\n\nsudo growpart /dev/nvme0n1 1\nNOCHANGE: partition 1 is size 209713119. it cannot be grown\n

Answer 1

我遇到了同样的问题用下面的命令解决了它（其他答案是错误的）

sudo growpart /dev/nvme0n1 1

然后我可以扩展 FS

sudo resize2fs /dev/nvme0n1p1

Answer 2

文件类型为 ext4。所以下面的命令有效。

sudo resize2fs /dev/nvme0n1p1
