overcloud install fails for br-ex network

Latest response

Hi,

I am having problems getting OSP10 based overcloud to install. the undercloud went in ok.

the system I am installing on has 2 compute and one controller nodes. i have tried several configurations without any success.

When I follow the troubleshooting instructions, I get down to the following

[stack@ostack2-director templates]$ openstack software deployment show 6afe6d18-d52f-4da7-87fd-39a877d4474c

I have br-ex defined on the controller and compute yaml files and have mapped in the network-environment file. The curious thing is that br-ex is part of an ovs-bridge that uses interface ens3f1 as the uplink, not nic1.

any clues where nic1 is coming from and why the correct nic is not being used?

I have included the two nic config files and the enviroment yaml files if that can give someone any clues. If there is any additional logs/data, please let me know.

one additional piece of data from the overcloud install log

[stack@ostack2-director ~]$ grep -i fail overcloud_install.log
2017-10-06 16:53:47Z [overcloud.AllNodesValidationConfig]: CREATE_IN_PROGRESHeat Stack create failed.
2017-10-06 17:29:59Z [overcloud.Compute]: CREATE_FAILED CREATE aborted
2017-10-06 17:29:59Z [overcloud]: CREATE_FAILED Create timed out
Stack overcloud CREATE_FAILED

I know the last two lines are from the fact that the timeout is set to 60 mins.. the initial failure at 16:53 was about 21 mins into the stack create.

Thanks in advance!
