我有一个运行 XCP-ng 8.2.1 的 XCP-ng 集群，在打上补丁并重启后，本地存储 SR 显示为未插电。这是 XCP 在 RAID 驱动器上创建的 LVM，相同的 RAID 驱动器包含正在启动的操作系统，我可以看到任何实际磁盘问题的证据。
要求堆栈插入 SR（在 XO 中或使用命令行）会导致相同的错误：

（注意非活动卷是思考正常，我在工作主机上看到这些，并且我也可以激活它，它会在短暂的时间后切换回非活动状态）。
我假设 LVM 存在一些问题，导致其无法插入 XCP，但找不到任何明显的错误或修复。查看存储日志，其中一个卷报告了一个错误，如下所示（来自 /var/log/SMlog，包含上下文和它们提供的任何信息的前几行 - 第 33 行及以后的错误“无法获取物理大小：-22”）：
