连接存储域出现问题（主机 host2 无法访问存储域）
大家好！我需要专家帮助，因为我已经绝望了。我公司有四台主机连接到存储。每个主机都有自己的 IP 来访问存储，这意味着主机 1有一个 ip10.42.0.10和10.42.1.10->主机 2有一个 ip10.42.0.20和10.42.0.20分别。主机 1无法 ping 该地址10.42.0.20。硬件我试图更详细地解释。
主机 1安装了 ovirt 节点 4.3.9 并部署了托管引擎。尝试将主机 2添加到集群时，它已安装，但未激活。ovirt 管理器出现错误 -"Host **host2** cannot access the Storage Domain(s) <UNKNOWN>"主机 2 进入“不可操作”状态。在主机 2上，它写道“connect to 10.42.1.10:3260 failed (No route to host)“在日志中并无限重复。我使用iscsiadm手动将主机2连接到存储到ip 10.42.0.20。但是错误并没有丢失（。同时，当主机尝试激活它时，我可以运行虚拟机直到主机显示错误消息。即使主机有Non-operational状态，已经在主机 2 上运行的虚拟机继续运行。我假设将主机 2添加到集群时，ovirt 尝试将其连接到同一个存储库主机 1从 ip 连接10.42.1.10。可能有一种方法可以让 ovirt 连接到另一个 ip 地址，而不是第一个主机的 ip 域地址。我正在附加日志：
