DG project does not get deleted

Environment

• Red hat OpenShift Container Platform (OCP)
  • 8.x
• Red Hat Data Grid (RHDG)
  • 8.x

Issue

• After deleting a project it still can be found
• oc delete deletes a project but it still there

Resolution

Steps:

1. check all the resources that are still inside the project and check which ones are not yet deleted
2. Most of the times it is a CRs, usually the cache crs.
3. ‘oc delete cr_type your-crd’ and check in the metadata section the part of finalizers and remove the elements of the array: oc edit cr_type your-Cr
4. save and exit
5. Some seconds later, the project should be removed

If it is not removed:

• Likely that there are still have other CRs in that project that were not removed
• the project itself has a finalizer that should be removed. In that case ‘oc edit project your-project’ and delete the metadata.finalizers section

Iterating over hang caches:

For a huge list of caches just do:

for CR in $(oc get cache -o name) ; do  oc patch $CR  -p '{"metadata":{"finalizers":null}}' --type=merge; done

Root Cause

Finalizers do not finalize the custom resources/project and hang for project deletion.
