Cluster Config multiple NICs for cluster traffic


Mar 20, 2019
**I have tried searching. However if an answer has been posted somewhere please drop a link.
**I debated if I should put this here or in if it is in the wrong place let me know.

I am able to configure a 2 node cluster no problem.

I am using directly connected 40gb NICs for cluster traffic.
I would like to add a second NIC in each server, these are 10gb and will also be directly connected.
This would be a backup for cluster traffic in the event something stops working in the 40gb connection.

the configuration is currently like this

node1 = 40gb IP=
node1 = 10gb IP=
node2 = 40gb IP=
node2 = 10gb IP=
Each node has 4x1gb cards for normal network communication

I added the 192.168.40 addresses to the host files and then created the cluster.

Everything works properly however I don't know how to let the cluster know that traffic can also go over the 192.168.10 links

I am sure it is something simple that I am overlooking.

Any help is appreciated.

Thank you Gosha for responding.

I think I worded my question poorly and that is my bad... sorry

I thought the ring0/1 settings were for cluster communication and I think I understand this part well enough...

I should have asked about migration settings, I think

In the datacenter.cfg like this....
keyboard: en-us
migration: type=insecure,network=

Can I have more than one "migration" entry so in case one fails?

Sorry again for not being clear.
