连接存储域的问题(主机host2无法访问存储域<UNKNOWN>)

Question

连接存储域的问题(主机host2无法访问存储域)

大家好！我需要专家的帮助，因为我已经绝望了。我的公司有四台主机连接到存储器。每个主机都有自己的IP来访问存储，这意味着主机1有ip 10.42.0.10，10.42.1.10 -> 主机2有ip 10.42.0.20和10.42.0.20。主机1不能平地址10.42.0.20。硬件我试着解释得更详细。主机1已经安装并部署了ovirt节点4.3.9。当尝试将主机2添加到集群时，它已安装，但未激活。在ovirt中有一个错误- "Host **host2** cannot access the Storage Domain(s) <UNKNOWN>"和主机2进入“非操作”状态。在主机2上，它在日志中写入"connect to 10.42.1.10:3260 failed (No route to host)“并无限期地重复。我使用iscsiadm将主机2手动连接到ip 10.42.0.20。但是这个错误并没有丢失。同时，当主机试图激活它时，我可以在它上运行虚拟机，直到主机显示错误消息。在主机2上运行的VMs即使在主机具有Non-operational状态时也继续运行。我假设当将主机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 10.42.1.10连接到的存储库。可能有一种方法可以使ovirt连接到另一个ip地址，而不是第一个主机的ip域地址。我在附上日志：

我在努力弄清楚你的建筑。您似乎已经配置了存储域，指向10.42.1.10:3260作为iSCSI门户。

如果我理解正确，那么您的集群应该如下所示：

     +-------------+
     |HostedEngine |
     +------+------+
            |
            |         Management network
    +-------+------+  10.42.0.0/24
    |              |
    +              +
10.42.0.10    10.42.0.20
+--------+    +--------+
| host1  |    | host2  |
+--------+    +--------+
10.42.1.10    10.42.1.20
    +              +
    |              |
    +-------+------+
            |
            |        Storage network
        +---+---+    10.42.1.0/24
        |Storage|
        +-------+

如果我的猜测是正确的，那么您似乎已经在host1上配置了您的host1目标，而不是一个适当的外部存储设备。否则，你就搞砸了IP地址。
