Environment:
RHACM 2.7.4, 2.8.0
Current Issue:
The user is creating clusters on vsphere using hive(ACM). They are observing that duplicate machinesets are getting created. Which means that the cluster is provisioning the cluster with 3 workers, but end up having 6 workers.The timestamps suggests that the duplicate machineset is getting created about 30minutes prior to one that’s created by the hive controller.
For example:
time="2023-06-16T18:55:00.33Z" level=info msg="found 1 remote machine sets" controller=machinepool machinePool=test02/test02-worker reconcileID=6bb4gnq6
time="2023-06-16T18:55:00.33Z" level=info msg="generated 1 worker machine sets" controller=machinepool machinePool=test02/test02-worker reconcileID=6bb4gnq6
time="2023-06-16T18:55:00.33Z" level=info msg="creating machineset" controller=machinepool machinePool=test02/test02-worker machineset=test02-6djhl-worker reconcileID=6bb4gnq6
time="2023-06-16T18:55:00.331Z" level=info msg="reconcile complete" clusterDeployment=test02/test02 controller=clusterState elapsedMillis=33 elapsedMillisGT=0 outcome=unspecified reconcileID=hfqzr77c
time="2023-06-16T18:55:00.344Z" level=info msg="reconcile complete" clusterDeployment=test02/test02 controller=clusterversion elapsedMillis=44 elapsedMillisGT=0 outcome=unspecified reconcileID=mw7c2d7f
~~~
Hive logs suggest that a machine set already existed before it created the second one.
There are no logs for test02-6djhl-worker-0 on the hive controller.
machine set timestamps:
- test02-6djhl-worker. ==> creationTimestamp: “2023-06-16T18:55:00Z”
- test02-6djhl-worker-0 ==> creationTimestamp: “2023-06-16T18:24:42Z”
Additional info:
Customer provisioned a cluster on azure using the same setup, but this issue was not faced
