Re: [Rdo-list] [RDO-Manager] deploy



Hi Dan,

Thanks for the description. As you described, iptables is running and MAC addresses for overcloud nodes are added as DROP rule properly. Only one interface is attached to the provisioning interface. But, overcloud nodes still load agent.kernel/ramdisk images, not deploy_kernel/ramdisk. Should I disable dhcp server @ other machine and setup new dhcp server on the same undercloud node?

This is my log:

On this deploying step, I can see deploy images/config are put to each instance's UUID directory @/httpboot/ directory. And then, the provisioning state is changed from [deploying] to [wait call-back]. Even though ipmitool turns on the system, those systems can't find deploy images.

Then, overcloud nodes could boot from agent.kernel/ramdisk from undercloud:/tftpboot properly. But, I don't know how overcloud nodes can get deploy/overcloud images.

If that default file is removed, system is unable to locate tftp configuration. How can I make controller/compute boot from right deploy images? Should I setup something for the httpboot/ipxe?

What is supposed to happen when introspection completes is that the
Undercloud will add the MAC address of the newly-discovered system to
iptables in order to block DHCP requests from reaching
ironic-discovery's dnsmasq. If that doesn't happen, then you get a loop
where the discovery image boots instead of the deploy image.

Check your iptables and make sure that you see the MAC addresses added
to the "discovery" chain, like this:

Chain discovery (1 references)
target     prot opt source   destination
DROP       all  --  anywhere anywhere             MAC 00:21:BA:17:0D:2B
DROP       all  --  anywhere anywhere             MAC 00:3C:A6:BB:68:FC
DROP       all  --  anywhere anywhere             MAC 00:92:5D:AE:62:37

Also, make sure that iptables is running, and that you don't have more
than one interface attached to the provisioning network on the
overcloud nodes. If you do, there is a workaround, but it's cleanest to
just make sure you have only one interface attached to the provisioning
interface.
