Hi,

I am trying to set up a 2 node cluster on a lab server using 2 VMs. I have tried the mesh as well as the multicast heartbeats but I run into different problems each time.

The heartbeats themselves seem to be OK but the cluster is never usable.

I checked the troubleshooting section as well but didn’t help. Then I came across this post([Cluster running Aerospike on LXC](https://discuss.aerospike.com/t/cluster-running-aerospike-on-lxc/1441)) but could not understand what exactly is to be done. Do I need some additional VM settings to make it work?

I have attached logs and conf of both the cases. Please help

Mesh Conf for node1: service { address any port 3000 access-address 192.168.254.132 virtual network-interface-name eth0 }

```
heartbeat {
	mode mesh
	address 192.168.254.132
	port 3002
            mesh-seed-address-port 192.168.254.132 3002
            mesh-seed-address-port 192.168.254.133 3002
            interface-address 192.168.254.132

	interval 150
	timeout 10
}

```

Multicast Conf for node 1: service { address any port 3000 access-address 192.168.254.132 virtual }

```
heartbeat {
	mode multicast
	address 239.1.99.1
	port 9918
            interface-address 192.168.254.132

	interval 150
	timeout 10
}

```

The conf files for the other node(192.168.254.133) are same with the obvious IP addresses changes.

I did not see the logs and config files. Please provide them again. You may have to use dropbox or google drive. What version of Aerospike you are running?

Hi HimanshuKumarSingh,

We ran into a similar scenario; our Test VM environment wasn’t responding as expected.

Issue: all of the nodes started up in a single node mode, even though a multicast configuration was used.

Resolution: the issue was easily resolved after adding the cluster aware configurations. See the online docs for additional information.

…hope this helps.
