@josephdrichard please have a look.
I'd say though, we do miss an automated test for it.
Yes, like that and to make sure it is part of the ZTP policy generator
@serngawy @imiller0 Could you guys please add it to the pipeline manifests? The need for patch is going to stay here for a while. As I understand it's not going to be handled by the PTP operator because there is a case where PTP benefits from NTP,
@vitus133 yes, we have it https://github.com/openshift-kni/cnf-features-deploy/blob/master/ztp/source-policy-crs/MachineConfigDisableChronyd.yaml
I believe @imiller0 included it in the pipeline for SNO testing
Yes. This machine config CR is part of the DU profile that is applied to clusters deployed through our ZTP pipeline.
Yesterday I added a validation in the ZTP metrics pipeline which checks that the chronyd machine config (disables chronyd) is applied to the active SNO MCP.
Thanks all and @imiller0 for the updates - seems like we can close this issue.
When using PTP Operator, it does contain the
phy2sys
which does time sync between PTP and the system. Having chronyd also active and doing clock sync, will be a conflict of two different processes (one with high time resolution other with regular time resolution) modifying the system clock. This affect workloads that rely on PTP and assume the system is also sync to PTP.Remediation:
