    vSAN Health check alarm during vMotions - ping large packet size

    andvm Enthusiast

      Hi,

       

      am noticing that while doing vMotions to a host, the vSAN health check shows an alert with failed ping with large packet size from the same host.

      MTU is set to 1500 from vSwitch on all hosts, could this be due to link saturation since using 1Gbps uplink or there is more to check? (migration succeed)

       

      Thanks

          If vMotion between the hosts is functional then it likely is just due to contention which causes some of the pings used for the Health test to be delayed or time-out and thus trigger the alert - I do recall there were some changes made to how this test functions to avoid this false-triggering in situations such as this but I cannot recall of the top of my head what build/version this is in.
