Re: Wrong resource consumption on scheduler



What node selector / tolerations / affinity rules were on your pod?  Is the pod under a service?

After giving the event log some thought, I realised that the 'Region fit failure' was a different error as 'Node didn't have enough resource', and realised that openshift is trying to force deployment onto node4.openshift.internal, a node I added recently. 

My nodes had these sets of labels: 


Removing the labels 'beta.kubernetes.io/arch=amd64,beta.kubernetes.io/os=linux' fixed the issue. 

Why is it so?

Hi, 

My pods are not deploying despite there being plenty of spare resources on my nodes; the event log on the pod seems to report much higher resource usage than what I'm seeing on my node: 

pod (redshiftlogger-14-8zaty) failed to fit in any node fit failure on node (node1.openshift.internal): Region fit failure on node (node2.openshift.internal): Region fit failure on node (node2.openshift.ncal): Region fit failure on node (node3.openshift.internal): Region fit failure on node (node4.openshift.internal): Node didn't have enough resource: Memory, requested: 2147483648, used: 32448771072, capacity: 32511942656

Restarting the master didn't help; I restarted one of two masters.
