OpenShift Container Platform - Node does not recognise newly added CPU or Memory

Solution Verified - Updated -


  • We have added more VCPU to computing nodes in our OpenShift 3.10 cluster. In fact we added 4 VCPU to the existing 4 CPU. Each computing node actually has 8 VCPU when checking with top on the computing node. But when checking the actual date in OpenShift, using oc describe nodes, the output under Allocatable CPU does only show 3600m, instead of 7600m.
