Static IP addressing? with Mellanox

[ed bond]

Hey All,

Anyone able to help me figure out now to get static IP’s allocated per machine for third party module required interfaces?

I am using the mellanox support charm to give each of my physical machines an IPoverIB interface. ( ib0 )

Is there a way for me to allow for a charm to write to /etc/network/interfaces ? Or another solution?

Should I be adding the Mac address of ib0 into MaaS even though it doesn’t get picked up during configuration and that network is closed to MaaS?


When I set the IP address manually, my charms get stopped because I messed with the config file.
2015-11-17 06:16:32 INFO juju.networker networker.go:163 networker is disabled - not starting on machine "machine-1"
2015-11-17 06:16:32 INFO juju.worker runner.go:269 start "authenticationworker"

This is because I modified the /etc/network/interfaces according to the code I looked into. 

What is the “Proper” Way to set up these interfaces so I can have a 54G backend for ceph / neutron?


The charm info I am using is:
  mellanox: 
    charm: "cs:trusty/mellanox-2"
    options: 
      "accept-mellanox-license": true
      md5sum: 5868da099e1c6a157a182898a4fb720b
      "ofed-file": "MLNX_OFED_LINUX-3.1-1.0.3-ubuntu14.04-x86_64.tgz"


Thanks in advance.
