我在 VMWare 上设置了一个拥有 50GB 的 ubuntu 服务器。
现在我的 ubuntu 说我没有足够的空间。indeeddf -h告诉我我的 ubuntu 只有 24G...
buzz@plex-vm:~$ df -h

我的 SSD（虚拟机位于其上）具有足够多的可用空间，并且在 Windows 中整个 SSD 是一个分区。
谢谢您的帮助。

好吧，我设法让它扩展 LV
lvextend -l+100%FREE /dev/mapper/ubuntu--vg-ubuntu--lv -A n：）
由于 LV 已满，自动备份阻止了 LV 扩展。因此，-A n将自动备份设置为否，以防有人遇到同样的问题。
