Hi, I'm facing overcloud failure at the same line related with 'Ensure system is NTP time synced' *The error below refer:-* *TASK [Ensure system is NTP time synced] ****************************************fatal: [overcloud-controller-0]: FAILED! => {"changed": true, "cmd": ["chronyc", "waitsync", "20"], "delta":......* *controller timedatectl:-* *[heat-admin@overcloud-controller-0 ~]$ timedatectl Local time: Tue 2020-10-27 08:53:19 UTC Universal time: Tue 2020-10-27 08:53:19 UTC RTC time: Tue 2020-10-27 08:53:19 Time zone: UTC (UTC, +0000) NTP enabled: yesNTP synchronized: no RTC in local TZ: no DST active: n/a* *undercloud timedatectl:-* * Local time: Tue 2020-10-27 17:36:11 +08 Universal time: Tue 2020-10-27 09:36:11 UTC RTC time: Tue 2020-10-27 09:36:11 Time zone: Asia/Singapore (+08, +0800) NTP enabled: yesNTP synchronized: yes RTC in local TZ: no DST active: n/a* Tripleo deployment for 1compute and 1controller. I have run few times and end-up with the same error. Seems it's all related to chrony. No more ntp in rocky release and all change to chrony to handle time synchronization. Based on my reading the issue should be resolved in rocky but clearly my overcloud deployment failed at this stage. Please advise how to resolve this problem. Thank you all.
