Hi Dmitry,

I might be wrong, but as per my understanding if there would be an issue in dnsmasq, then IP 20.20.20.10 would not have been assigned to the machine.

TCPDUMP logs are as below:

20:16:58.938089 IP controller.bootps > 255.255.255.255.bootpc: BOOTP/DHCP, Reply, length 312

Also the neutron dnsmasq logs and ironic inspector logs are attached in the mail.

Hi,

You need to check the dnsmasq logs (there are two dnsmasqs: from neutron and from ironic-inspector). tcpdump may also help to determine where the packages are lost.

Hi Dmitry

Thanks for your time.

My system is getting IP 20.20.20.10 which is in the range defined in ironic_dnsmasq_dhcp_range field under globals.yml file.

ironic_dnsmasq_dhcp_range: "20.20.20.10,20.20.20.100"

And in the cleaning network (public1), the range defined is 20.20.20.150-20.20.20.200

As per my understanding, these 2 ranges should be mutually exclusive.

Please suggest if my understanding is not correct.

Any suggestions what should I do to resolve this issue?

Hi Team,

In  to the email below, I have some updated information:-

Earlier the allocation range mentioned in "ironic_dnsmasq_dhcp_range" in globals.yml had an overlapping range with the cleaning network, due to which there was some issue in receiving the DHCP request 

After creating a cleaning network with a separate allocation range, I am successfully getting IP allocated to my Baremetal Node

• openstack subnet create subnet1 --network public1 --subnet-range 20.20.20.0/24 --allocation-pool start=20.20.20.150,end=20.20.20.200 --ip-version=4  --gateway=20.20.20.1 --dhcp

After getting the IP, there is no further action on the node. >From "clean_wait", it goes into "clean_failed" state after around half an hour.

The IP address is not from the cleaning range, it may come from inspection. You probably need to investigate your network topology, maybe use tcpdump.

Unfortunately, I'm not fluent in Kolla to say if it can be a bug or not.

On verifying the logs, I could see the below error messages

• In /var/log/kolla/ironic/ironic-conductor.log, we observed the following error:

ERROR ironic.conductor.utils [-] Cleaning for node 3a56748e-a8ca-4dec-a332-ace18e6d494e failed. Timeout reached while cleaning the node. Please check if the ramdisk responsible for the cleaning is running on the node. Failed on step {}.

Note : For Cleaning the node, we have used the below images

 https://tarballs.openstack.org/ironic-python-agent/dib/files/ipa-centos8-master.kernel

 https://tarballs.openstack.org/ironic-python-agent/dib/files/ipa-centos8-master.initramfs

• In /var/log/kolla/nova/nova-compute-ironic.log, we observed the error

Can someone please help in this regard?

Hi Team,

We have deployed 2 node kolla ansible 12.0.0 in order to deploy openstack wallaby release. We have also enabled ironic in order to provision the bare metal nodes.

On each server we have 3 nics

• eno1 - OAM for external connectivity and endpoint's publicURL
• eno2 - Mgmt for internal communication between various openstack services.
• ens2f0 - Data Interface

Corresponding to this we have defined the following fields in globals.yml

• kolla_base_distro: "centos"
• kolla_install_type: "source"
• openstack_release: "wallaby"
• network_interface: "eno2"                               # MGMT interface
• kolla_external_vip_interface: "eno1"               # OAM Interface
• kolla_internal_vip_address: "192.168.10.3"    # MGMT Subnet free ip
• kolla_external_vip_address: "10.0.1.136"       # OAM subnet free IP
• neutron_external_interface: "ens2f0"             # Data Interface
• enable_neutron_provider_networks: "yes"

Note: Only relevant fields are being shown in this query

Also, for ironic following fields have been defined in globals.yml

• enable_ironic: "yes"
• enable_ironic_neutron_agent: "{{ enable_neutron | bool and enable_ironic | bool }}"
• enable_horizon_ironic: "{{ enable_ironic | bool }}"
• ironic_dnsmasq_interface: "ens2f0"                       # Data interface
• ironic_dnsmasq_dhcp_range: "20.20.20.10,20.20.20.100"
• ironic_dnsmasq_boot_file: "pxelinux.0"
• ironic_cleaning_network: "public1"
• ironic_dnsmasq_default_gateway: "20.20.20.1"

After successful deployment, a flat provider network with the name public1 is being created in openstack using the below commands:

• openstack network create public1 --provider-network-type flat --provider-physical-network physnet1
• openstack subnet create subnet1 --network public1 --subnet-range 20.20.20.0/24 --allocation-pool start=20.20.20.10,end=20.20.20.100 --ip-version=4  --gateway=20.20.20.1 --dhcp

Issue/Queries:

• Is the configuration done in globals.yml correct or is there anything else that needs to be done in order to separate control and data plane traffic?

• Also I have set automated_cleaning as "true" in ironic-conductor conatiner settings.But after creating the baremetal node, we run "node manage" command which runs successfully. Running "openstack baremetal node provide <node id>" command powers on the machine, sets the boot mode on Network Boot but no DHCP request for that particular mac is obtained on the controller. Is there anything I am missing that needs to be done in order to make ironic work?

Note: I have also verified that the nic is PXE enabled in system configuration setting

Regards
