Hi, I am trying to deploy a new platform using kolla-ansible Yoga and I am trying to upgrade another platform from Xena to yoga. On both platforms the prechecks went well, but when I start the process of deployment for the first and upgrade for the second, the process gets stuck. I tried to tail -f /var/log/kolla/*/*.log but I can't get hold of the cause. In the first platform, some services get deployed, and at some point the script gets stuck, several times in the modprobe phase. In the second platform, the upgrade gets stuck on : Escalation succeeded [204/1859] <20.3.0.28> (0, b'\n{"path": "/etc/kolla/cron", "changed": false, "diff": {"before": {"path": "/etc/kolla/cro n"}, "after": {"path": "/etc/kolla/cron"}}, "uid": 0, "gid": 0, "owner": "root", "group": "root", "mode": "07 70", "state": "directory", "secontext": "unconfined_u:object_r:etc_t:s0", "size": 70, "invocation": {"module_ args": {"path": "/etc/kolla/cron", "owner": "root", "group": "root", "mode": "0770", "recurse": false, "force ": false, "follow": true, "modification_time_format": "%Y%m%d%H%M.%S", "access_time_format": "%Y%m%d%H%M.%S", "unsafe_writes": false, "state": "directory", "_original_basename": null, "_diff_peek": null, "src": null, " modification_time": null, "access_time": null, "seuser": null, "serole": null, "selevel": null, "setype": nul l, "attributes": null}}}\n', b'') ok: [20.3.0.28] => (item={'key': 'cron', 'value': {'container_name': 'cron', 'group': 'cron', 'enabled': True , 'image': '20.3.0.34:4000/openstack.kolla/centos-source-cron:yoga', 'environment': {'DUMMY_ENVIRONMENT': 'ko lla_useless_env', 'KOLLA_LOGROTATE_SCHEDULE': 'daily'}, 'volumes': ['/etc/kolla/cron/:/var/lib/kolla/config_f iles/:ro', '/etc/localtime:/etc/localtime:ro', '', 'kolla_logs:/var/log/kolla/'], 'dimensions': {}}}) => { "ansible_loop_var": "item", "changed": false, "diff": { "after": { "path": "/etc/kolla/cron" }, "before": { "path": "/etc/kolla/cron" } }, "gid": 0, "group": "root", How to start debugging the situation.
