TL;DR: How to set up MAAS, without the maas-server providing DHCP?
I am having a problem with a MAAS cluster setup, since it's on a subnet that already has a DHCP/DNS provider on it, over which I do not have control.
My overall goal is to set up the cluster via MAAS and deploy Hadoop via Juju.
8 nodes: 1 Region and rack controller aka. master, 7 slave aka. 01, 02 ect.
They each have PXE boot enabled. Boot order: Network, USB/CD, HDD
(Power type set to 'Manual' in MAAS, see below)
Network:
Gateway: 192.168.X.1
Static IPs can be assigned in the range 192.168.X.16-24, but only in the node's config, not via DHCP provider (Gateway/Router).
DHCP provider gives IPs in the range: 192.168.X.65 - 254. I set this range as 'Reserved dynamic range' in MAAS
So my problem begins here: I see my nodes in 'Device discovery' but from there, I can only add them as a 'Device' not as a 'Machine'.
I can only manually add the nodes to MAAS as Machines, (getting their MAC address is no problem) but they fail to comission; time out.
I (desperately) tried to set them to a static IP address, and add them to MAAS that way, (/etc/network/interfaces file) they still fail to comission.
MAAS troubleshoot - faq points me at this:
If you are using MAAS in a setup with an existing DHCP, DO NOT SET UP THE MAAS DHCP SERVER [...]
SOLUTION: You will need to configure your existing DHCP server to point to the MAAS server.
Which is something I can't do in my current situation.
What steps do I need to take to make this work?
This might be a trivial question, but I am a complete beginner in the topic.
Ps.: If a static solution is possible, it's good enough for me. In case this problem cannot be solved under the circumstances described above, then I would like to hear a solution that's changing as little of the (physical) setup as possible.
