如何在不丢失数据的情况下动态扩展 CentOS v8 VM 磁盘空间?

如何在不丢失数据的情况下动态扩展 CentOS v8 VM 磁盘空间?

我需要一些可以从 Putty 会话中遵循的步骤,以便我可以扩展 CentOS v8 VM 而不丢失其数据?

我已经将 VMDK 中的磁盘空间从最初的 40 GB 扩展到 60 GB。

Welcome to fdisk (util-linux 2.32.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

磁盘空间好像还是一样,但是 FS 好像有点不一样?

如何纠正上述问题?

先感谢您。
