Add node to a new Cluster (Fail)

[masterdaweb]

I'm trying to add a Node to a Cluster but it always fails, I'm using 2 dedicated servers from OVH.

Take a look at the error below:

=====================================================
root@ns516885:~# pvecm add 158.69.240.50

=======================================================


Then when I use 'systemctl status corosync.service' to check what went wrong, it shows me:

I'm trying to add a Node to a Cluster but it always fails, I'm using 2 dedicated servers from OVH.

Does multicast between those nodes works? AFAIK this needs OVH vRack.

Is it possible to make it work using unicast? Cause I don't have a vRack.

How to figure out without using multicast ? Thanks

I did, but it is still not working.
Node appears but it stays down.

bindnetaddr looks wrong to me?

 

[masterdaweb]

bindnetaddr looks wrong to me?

I already tried cluster IP, but I got the same error listed above.

I tried then 0.0.0.0 cause Unicast tutorial says to use it if nodes are not in the same subnet.

I really wish that it could work, I tried everything
