Hello,
I have a virtual machine scale set configured for AKS cluster, that has no autoscaling enabled (just 2 instances). All of a sudden, 5 days ago, I have noticed the nodes have switched to Not Ready state, even though I have not applied any changes, configuration updates, etc.
I have already tried upgrading nodes and updating images, as well as restarting both AKS service and virtual machine scale set, but no luck. It has been 5 days since it has been down and I am not able to identify the cause.
When I run kubectl describe nodes, I get the following:
Normal Starting 19s kubelet Starting kubelet.
Warning InvalidDiskCapacity 13s kubelet invalid capacity 0 on image filesystem
Normal Starting 13s kubelet Starting kubelet.
Warning InvalidDiskCapacity 7s kubelet invalid capacity 0 on image filesystem
Normal Starting 7s kubelet Starting kubelet.
Normal NodeHasSufficientMemory 7s kubelet Node aks-nodepool1-20474252-vmss000009 status is now: NodeHasSufficientMemory
Warning InvalidDiskCapacity 2s kubelet invalid capacity 0 on image filesystem
Normal Starting 2s kubelet Starting kubelet.
Any help will be appreciated.
Thanks!
