我试图在VCenter上扩展一个LVM组，但没有取得太大的成功。
我遵循这个指南来扩展虚拟机磁盘，并创build新的主分区/dev/sda3 。 当我继续使用pvcreate -vv /dev/sda3命令时，我得到：
# pvcreate -vv /dev/sda3 Setting activation/monitoring to 1 Setting global/locking_type to 1 Setting global/wait_for_locks to 1 File-based locking selected.

Unlocking /run/lock/lvm/P_orphans
以下是类似post的一些输出：

我迷失在如何能够扩展这个LVM而不能添加新的分区！
谢谢
为了在线resize，我创build了一个小脚本来生成所需的命令。 请参阅： https ： //github.com/mircea-vutcovici/scripts/blob/master/vol_resize.sh
它涵盖了Linux上使用的最stream行的磁盘标签和文件系统。
您可以在不重新启动机器的情况下完成所有这些调整。
