我们有一台采用 Raid 1 配置的 Dell PowerEdge R920（Perc H730P：raid 控制器）。我成功将 raid 卷从 2x 300Gb 磁盘升级到 2x 600Gb 磁盘。
现在，我需要在 CentOS 上的 LVM 上扩展逻辑卷，但我无法创建任何分区：没有可用的空闲扇区。但是磁盘在 fdisk 上被识别，我可以在 gparted 上看到未分配的空间。

但我无法创建任何分区：

我无法停用 gparted 上的分区Logical volume VolGroup/lv_root contains a filesystem in use. Can't deactivate volume group "VolGroup" with 3 open logical volume(s)
有人有什么想法吗？谢谢

您正在尝试使用 fdisk 在 GPT 标签上创建分区。它报告说，这不起作用。请尝试使用支持 GPT 的分区工具，例如 parted。
您可以在这里找到描述：https://www.thegeekdiary.com/how-to-create-a-partition-using-parted-command/
