问题描述

无法访问CIFS共享。
LIF无法访问网关、已超时。
EMS中报告了以下错误：

::> event log show Time Node Severity Event ------------------- ---------------- ------------- --------------------------- 7/5/2024 13:21:26 Node-01 ERROR dns.server.timed.out: DNS server 172.xx.xx.xx did not respond to vserver = SVM within timeout interval. 7/5/2024 13:21:01 Node-01 ERROR secd.cifsAuth.problem: vserver (SVM) General CIFS authentication problem. Error: Get DC connection latency times procedure failed ... [ 6067] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host. [ 6069] Unable to connect to NetLogon service on cyinazcorpadc.corp.cyient.com (Error: RESULT_ERROR_SPINCLIENT_UNABLE_TO_RESOLVE_SERVER) [ 6069] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host. [ 6071] Unable to connect to NetLogon service on cyinklkadc.corp.cyient.com (Error: RESULT_ERROR_SPINCLIENT_UNABLE_TO_RESOLVE_SERVER) [ 6072] TCP connection to ip 172.xx.xx.xx, port 445 failed: No route to host.

Vserver具有已正确配置的路由：

示例：

Cluster::> network route show -vserver VS1 Vserver Destination Gateway Metric ------------------- --------------- --------------- ------ VS1 0.0.0.0/0 192.168.1.1 20

注意： 由于多个默认网关具有相同指标、名称服务失败- NetApp知识库

接口与网关接口位于同一子网：

示例：

Cluster::> network interface show -vserver VS1 Logical Status Network Current Current Is Vserver Interface Admin/Oper Address/Mask Node Port Home ----------- ---------- ---------- ------------------ ------------- ------- ---- VS1 VS1-LIF1 up/up 192.168.1.50/24 Cluster-01 a0a-100 true

注意：在上述示例中、网关配置为位于192.168.1.1上、LIF配置为位于192.168.1.0/24网络中、表示该网络应位于同一子网中、因此可以排除子网划分错误。

LIF的端口运行状况良好

示例：

::> network port show Port IPspace Broadcast Domain Link MTU Admin/Oper Status --------- ------------ ---------------- ---- ---- ----------- -------- a0a Default vlan101 up 1500 auto/10000 healthy a0a-100 Default vlan101 up 1500 -/- healthy
