Verified: Executed regression job(which was reason for original commit): https://rhos-qe-jenkins.rhev-ci-vms.eng.rdu2.redhat.com/view/DFG/view/df/view/controller_replacement/job/DFG-df-controller_replacement-16-virthost-3cont_3comp_3ceph-yes_UC_SSL-yes_OC_SSL-ceph-ipv4-geneve-replace_controller-corrupt_disk-RHELOSP-38495/7/ In addition checked with submitter and he stated: The problem I hit was fixed by this patch: https://code.engineering.redhat.com/gerrit/#/c/187649/ which is a revert of an earlier patch. Above patch was committed to fix this bug. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA. For information on the advisory, and where to find the updated files, follow the link below. If the solution does not work for you, open a new bug report. https://access.redhat.com/errata/RHEA-2020:0283 |
When config download runs to generate the ansible project directory, it will fail if any host shortname starts with another host's shortname. Particularly, this will happen when deploying with more than 10 nodes of the same roles and using the default hostname formats since a hostname such as openstack-compute-10 starts with openstack-compute-1. Sample traceback of a host called compute-2, and I also have hosts compute-20, compute-21, etc: Traceback (most recent call last): File "/usr/bin/tripleo-config-download", line 57, in <module> stack_config.download_config(args.stack_name, args.output_dir) File "/home/centos/tripleo-common/tripleo_common/utils/config.py", line 577, in download_config self.write_config(stack, name, config_dir, config_type) File "/home/centos/tripleo-common/tripleo_common/utils/config.py", line 515, in write_config if role_host_vars and server_role: SystemError: Found multiple `compute-2`, which is unexpected.
