What if controller runs out of resources / how to migrate to new machine

I installed controller on a ec2 machine via k3d k8s cluster and due to some reason the underlying disk has become full and pods give reason as disk-pressure for not getting scheduled .

I think during this time some policies also gets deleted .

But yeah to be safe please tell me if increasing ebs and restarting the instance is good way or we can migrate the storage to some external store like s3 something

What is the best and easy way to handle this situation ?

fixed by increasing EBS
