![如何创建可用盘区,以便替换此 lvm 卷组中的物理驱动器?](https://linux22.com/image/141960/%E5%A6%82%E4%BD%95%E5%88%9B%E5%BB%BA%E5%8F%AF%E7%94%A8%E7%9B%98%E5%8C%BA%EF%BC%8C%E4%BB%A5%E4%BE%BF%E6%9B%BF%E6%8D%A2%E6%AD%A4%20lvm%20%E5%8D%B7%E7%BB%84%E4%B8%AD%E7%9A%84%E7%89%A9%E7%90%86%E9%A9%B1%E5%8A%A8%E5%99%A8%EF%BC%9F.png)
我有一个 Fedora Linux 28 系统,有 4 个物理驱动器合而为一LVM Volume Group
。该系统的主板只有 4 个 SATA 插槽。我的目标是/dev/sdd
从卷组中删除物理驱动器。我在安装 Fedora 期间设置了这个 LVM 卷组,此后我没有对其进行任何更改。
sudo lvm pvdisplay -m

我正在尝试跟随本指南,它描述了如何使用该pvmove
命令,但运行时pvmove /dev/sdd1
出现此错误:
No extents available for allocation.
