问题描述

  • 更换主板后出现MTU不匹配。
 
Sun Oct 06 15:03:40 JST [Node-01: vifmgr: vifmgr.cluscheck.mtumismatch:alert]: MTU 1500 on cluster port e0f (node Node-01) does not match MTU 9000 on cluster port e0e (node Node-02).
 
  • 然后、由于MTU数据包丢失较大、会发生CLUSTER NETWORK DEGRADED 。
 
Mon Oct 07 15:00:53 JST [Node-02: vifmgr: vifmgr.cluscheck.ctdpktloss:alert]: Continued packet loss when pinging from cluster lif Node-02_clus2 (node Node-02) to cluster lif Node-01_clus2 (node Node-01).
Mon Oct 07 15:07:43 JST [Node-02: vifmgr: callhome.clus.net.degraded:alert]: Call home for CLUSTER NETWORK DEGRADED: Large MTU Packet Loss - Ping failures detected between Node-02_clus1 ( XXX.XXX.XX.X ) on Node-02 and Node-01_clus2 ( XXX.XXX.XX.XX ) on Node-01
 
  • 端口MTU已从9000修改为1500。
