在 VMWare 中增加虚拟磁盘不会显示 LVM 中有新可用空间

我在 VMWare ESXi 4.1 虚拟机上将虚拟硬盘的大小从 79GB 增加到了 100GB

之后我重新启动了虚拟机，但是当我进入虚拟机时

[root@linxuph53]# vgdisplay
  --- Volume group ---
  VG Name               vg_linuxph53

  VG UUID               Y269kC-3Jzh-hSHz-Jgwv-lkVO-K69T-mzrqaZ

我没有看到我有新的未分配空间，所以从技术上讲我无法扩展我的 /home 分区

  --- Logical volume ---

有任何想法吗？

重新启动虚拟机并运行 fdisk -l 后

这就是我所看到的

  [root@linxuph53 semenov]# fdisk -l

谢谢，德米特里

您可能需要重新启动虚拟机才能重新读取分区表。您可以尝试该partprobe命令，看看输出是否发生了变化fdisk -l，但重新启动肯定可以解决问题。
