STATUS_IO_TIMEOUT, ERROR_TIMEOUT, STATUS_CLUSTER_CSV_AUTO_PAUSE_ERROR
Article ID: HPV0003 Error occurs when a backup operation is initiated on a Windows 2012 based Cluster Shared Volume.
The following events have occurred:
- The backup was created, but the virtual machine entered into a paused state.
- The Windows 2012 Cluster Shared Volume (CSV) went offline, thereby causing the virtual machine to go offline.
The backup operation fails with any one of the following storage errors, as indicated in the Failover Cluster Manager:
During the backup operation, while a snapshot of the Cluster Shared Volume (CSV) is created, the virtual machine enters a paused state because the Ntfs.sys driver incorrectly reports the available space on the CSV. The CSV volume eventually goes offline because it does not resume from a paused state after an I/O delay issue or error occurs.
