我在 vmware 上运行一个虚拟机，它只分配了 17gig 的空间，我将 vmware 中的硬盘大小从 17gig 更改为 100gig。
这是虚拟机的信息，如何将容量从 17gig 扩展到 100gig？

答案1
您需要调整分区 sda1 的一侧以获得更大的一端。如果您很小心，您可以只使用 fdisk，然后删除并重新创建它。只需确保您具有完全相同的起始扇区和类型。
完成此操作后，您应该能够运行pvresize /dev/sda1以扩展 LVM 中的可用空间。然后，您可以使用调整逻辑卷的大小lvresize，最后调整所包含的文件系统的大小（如果是 ext2/3/4，则使用）resize2fs。
