我有一个带有 2 个虚拟机的 VMWare Server 3.5 系统。在其中一个启动的虚拟机上，我将磁盘大小从 1TB 更改为 1.5TB。但虚拟机没有看到任何新的未分配空间，因此我重新启动了两次服务器。但什么也没发生... 客户机上的操作系统是 CENTOS，两个磁盘是 LVM。fdisk 看到新空间... 但磁盘上没有分区... lvm 没有看到任何可用空间...
[root@srv-archive ~]# dmesg |grep sdb

我只想扩展我的 lvm 设备..非常感谢 cheers luigi
答案1
您可能想尝试不同的方法：
- Power down the VM
- Create a new disk for the VM using the VMWARE control panel with the additional size you want
- do a pvcreate on the new disk
- do a vgextend adding the new disk
- then you can do whatever lvextend you need.
- REMEMBER the filesystems will need to be extended as well.
答案2
您尝试过吗pvresize /dev/sdb？这是因为您的磁盘大小已更改但lvm您还不知道。
