    What action should i take?

    Volume flush-and-hold IOCTL was detected on clustered shared volume

    Because of the design of Cluster Shared Volumes, backup applications for these volumes must meet specific requirements for compatibility. The Cluster Shared Volumes feature allows volumes in cluster storage to be accessed by all nodes of a failover cluster. This makes it possible for virtual machines to use volumes on the same LUN (disk) while still being able to fail over (or move from node to node) independently of one another.

    Message: A backup application initiated a VSS snapshot on Cluster Shared Volume '%1' ('%3') without properly preparing the volume for snapshot. This snapshot may be invalid and the backup may not be usable for restore operations. Please contact your backup application vendor to verify compatibility with Cluster Shared Volumes.
