Hi, ee use the ping check to see whether the host running hosted engine has connectivity with the rest of the cluster and users. We kill the VM in a hope that some other host will make the engine available to users again. We use the gateway by default as it is pretty common to have separate

Hi, I have seen hosts rendered unresponsive when gateway is lost. I will be able to provide more info once I prepare an environment and test this further. Thanx, Alex On Tue, Feb 6, 2018 at 10:40 AM, Yaniv Kaul wrote: > > > On Feb 5, 2018 2:21 PM, "Alex K"
