This article describes an issue that occurs when you use the Volume Shadow Copy Service (VSS) backup on a Cluster Shared Volumes (CSV) volume by using a software snapshot provider in Windows Server 2012 R2 or Windows Server 2012. A hotfix is available to fix this issue. The hotfix has a prerequisite.
Symptoms
When multiple VSS backups are in progress, the cluster service may crash because of an inconsistent state of the CSV VSS provider. In this situation, all virtual machines go offline because of the CSV failure.
Cause
This problem occurs because of a race condition that causes the cluster service to reach a state when multiple CSV VSS software snapshots are initiated. This causes an exception that leads to a null pointer access.
