如何扩展 Oracle Linux Server 7.9 上的 /dev/sda3 的空间

磁盘容量为 105GB，但根目录 (/dev/sda3) 容量只有 39GB，我想增加容量。该怎么做？顺便说一下，操作系统是 Oracle Linux Server 7.9。

我尝试了所有方法，但还是没能成功。我感觉我漏掉了一些步骤。

$ resize2fs /dev/sda3
resize2fs 1.45.4 (23-Sep-2019)
resize2fs: Bad magic number in super-block while trying to open /dev/sda3
Couldn't find valid filesystem superblock.

$ xfs_growfs /dev/sda3 -D size

data size unchanged, skipping
