Fleet server agent with ECK operator in OpenShift deploying error

Error: preparing STATE_PATH(/usr/share/elastic-agent/state) failed: mkdir /usr/share/elastic-agent/state/data: permission denied

I got this error while the deploying of fleet server using this configuration in manifest file:

      creationTimestamp: null
      automountServiceAccountToken: true
          name: agent
          resources: {}
        privileged: true
        runAsUser: 0


Here is a response I got from a colleague:

The securityContext looks good with runAsUser: 0 and privileged: true . Maybe he missed the step to correctly configure the ServiceAccount used to deploy the Agent resource: Grant host access permission to Elastic Agent | Elastic Cloud on Kubernetes [2.13] | Elastic.

About the second thing: this involves preparing the directory (in particular executing chcon -Rt svirt_sandbox_file_t "${dir}" ). It seems to me that this is only necessary if you want to deploy the agent as non-root, not the case here.
We tried to do something in the operator, see Automatically adjust Elastic Agent hostPath permissions by naemono · Pull Request #6599 · elastic/cloud-on-k8s · GitHub

There could be something odd with your storage setup. Could you give more details of their cluster (version; storage; etc)?
