Hi folks, We are seeing some weird issues with multiple compute nodes and would appreciate your thoughts. Background:We are on stable Queens.As part of an upgrade to accomodate 3X more servers, we decided to add three more compute nodes+ three more ICs for a total of 6 compute nodes and 6 ICs.As soon as we added these in preparation for the 3X increase in servers I am seeing weirdbehaviour. A general question to everyone:How many of you run your baremetal clouds with 5+ computes and ICs?Are things stable with the setup ? Logs and Analysis:all compute and conductor services are up and running. 1) Baremetal node c1bda753-d46c-4379-8d07-7787c2a4a7f2 mapped to sc-ironic08root@stg-cl1-dev-001:~# openstack hypervisor show c1bda753-d46c-4379-8d07-7787c2a4a7f2 | grep ironic | | service_host | sc-ironic08.nvc.nvidia.com 2)Mac address is 6c:b3:11:4f:8a:c0root@stg-cl1-dev-001:~# openstack baremetal port list --node c1bda753-d46c-4379-8d07-7787c2a4a7f2+--------------------------------------+-------------------+| UUID | Address |+--------------------------------------+-------------------+| a517fb41-f977-438d-8c0d-21046e2918d9 | 6c:b3:11:4f:8a:c0 |+--------------------------------------+-------------------+ 2)Provisioning starts: ironic06 receives the VIF update: WHY ?2020-04-21 15:05:47.509 71431 INFO ironic.conductor.manager VIF 657fea31-3218-4f10-b6ad-8b6a0fa7bab8 successfully attached to node c1bda753-d46c-4379-8d07-7787c2a4a7f2 ironic08 (correct one) also receives updates.[root@sc-ironic08 master_images]# tail -f /var/log/ironic/ironic-conductor.log | grep c1bda753-d46c-4379-8d07-7787c2a4a7f22020-04-21 15:08:04.943 27542 INFO ironic.conductor.task_manager [req-259b0175-65bc-4707-8c88-a65189a29954 - - - - -] Node c1bda753-d46c-4379-8d07-7787c2a4a7f2 moved to provision state "deploying" from state "wait call-back"; target provision state is "active" For now we have backed down to 3 and are stable again but I would really like to overprovision our computes and conductors if possible. Please let me know your thoughts and if anything rings a bell. thanks,Fred.
