/kind bug

What happened:

Using vsphere as cloud provider, we created a storageclass and use PersistenVolumeClaims.

VMDKs get created and attached to machines - but when a pod dies, it takes like 5-15 minutes to attach the disk to another VM. The k8s API - or the volume plugin tries to attach a disk when it is still attached to another machine, same for deletion: The volume plugin tries to delete a disk subjectively a million times, this causes error showing in the VSphere console.

Is this normal?

What you expected to happen:

No errors in VSphere

How to reproduce it (as minimally and precisely as possible):

Simply kill a pod using a volume or delete a deployment
