Cluster on specific interface

[lweidig]

We are in the process of rebuilding (well creating new) a cluster running on 4.0. We have three interfaces on each of the machines. Two 1G which are front facing and used for accessing the virtual machines with public IP space and a 10G used for our storage network running on private IP space. We want to start building the cluster but want the cluster management to be on the 10G interface.

How do we specify this when creating the cluster initially? Does it look for the first entry in the /etc/hosts file? I recall this being an issue when we created our 3.x cluster but cannot find what was needed exactly to get this working.

No, It resolves 'hostname' with /etc/hosts, and use that address.

Thanks for the quick reply. My suggestion would be to create this as a parameter that can be passed on the cluster creation command so that you can specify the host / interface you want. Just makes things more flexible for setup.

AFAIK this is already implemented, see
