I thought about doing this today, but didn't think of a good way around the problem of hanging dependent objects. Clearing the finalizers from broken StorageClusters and other CRDs from failed installs is bound to be a manual process.

I can work through completing this action in a healthy cluster (tearing down each element and waiting for the operators to gracefully finalize), but I think the command is more intended for unhealthy clusters.

Is your heart set on automating this for even unhealthy OCS deployments?

Listing stuck resources

oc api-resources --verbs=list --namespaced -o name | xargs -n 1 oc get --show-kind --ignore-not-found -n openshift-storage | grep -v ^packagemanifest.packages.operators.coreos.com | grep -v ^NAME | awk '{ print $1 }'

Attempt forceful delete

oc delete --grace-period=0 --force --wait=false storagecluster.ocs.openshift.io/ocs-storagecluster

Remove Finalizers

oc patch storagecluster.ocs.openshift.io/ocs-storagecluster --type=merge -p '{"metadata": {"finalizers": null}}'

One command to rule them all.

export NAMESPACE=openshift-storage; oc api-resources --verbs=list --namespaced -o name | xargs -n 1 oc get --show-kind --ignore-not-found -n $NAMESPACE 2>/dev/null | grep -v ^packagemanifest.packages.operators.coreos.com | grep -v ^NAME | awk '{ print $1 }' | xargs -rI % oc patch % --type=merge -p '{"metadata": {"finalizers": null}}' -n $NAMESPACE
