multipath -ll 不显示任何输出

multipath -ll 不显示任何输出

这是我的 Centos 7。我将其从一个位置移动到另一个位置,本地支持人员添加了正确的电缆以将 SAN 磁盘呈现给服务器,但我在多路径中没有看到任何输出。服务器已重新启动并且多路径服务正在运行,但抱怨 sdc

如果我将它与其他类似的服务器进行比较,我可以看到正确的多路径输出

请建议,如何修复多路径。谢谢

编辑-我能够解决它。据我记得,我在 /etc/lvm/lvm.conf 中设置了“obtain_device_list_from_udev = 0”和“use_lvmetad = 0”并重新启动了服务器,我能够看到/home。
