Virtual Standby Exports Fail with Error, "The driver change log file is not large enough to accommodate the changes in the data" (4041084)

Virtual Standby Exports Fail with Error, "The driver change log file is not large enough to accommodate the changes in the data"

Virtual Export jobs are failing with error message:

ERROR 2015-06-08T21:21:24 [407] - Replay.Core.Implementation.Export.VirtualMachineExporterWindows (Post-processing volume(s)) Mount failed with exception System.InvalidOperationException: The driver change log file is not large enough to accommodate the changes in the data at Replay.Common.Implementation.Virtualization.VirtualMachineBuilderWindows.UpdateDriverChangeLogFile(IVolumeMetadata volumeMetadata, IBitmap blocksToCopy, IEnumerable`1 driverChangeLogFileLogicalExtents) at Replay.Common.Implementation.Virtualization.VirtualMachineBuilderBase.WritePostProcessingChangesToVolume(IVolumeMetadata volumeMetadata, IVolume volume, IEnumerable`1 driverChangeLogFileLogicalExtents, IBitmap blocksToCopy) at Replay.Core.Implementation.Export.VirtualMachineExporterWindows.TryPostProcessVolume(IPAddress replayServerAddress, ILocalMount& localMount, String& onDiskMountPoint, String mountPoint, IVolumeImage volumeImage, ExporterSourceVolume exporterSourceVolume, MountFlags mountFlags) at Replay.Core.Implementation.Export.VirtualMachineExporterWindows.PostProcessExportedVolume(ExporterSourceVolume exporterSourceVolume, IPAddress replayServerAddress, String mountPointBasePath)

The protected machine has a volume that is very full, and it may be causing other errors such as volsnap 41 and backup failures to the Core. If these backup failures are consistently happening, then resolving the backup failure issue will fix the virtual export problems related to the error message above.

WORKAROUND 1:

Verify that your AppAssure build is not below 5.4.2.x. If it is, upgrade to the latest AppAssure release with update patch by navigating to our Download New Releases page.

WORKAROUND 2:

On the source machine, verify in the Core Console events that the troubled machine not failing backups. If it is failing backups, search the error message in our Knowledge Base for a possible solution. Once resolved, monitor the backup jobs and the immediate virtual export. Perform a defragmentation of the Agent's volumes. If issues persist, open a service request with AppAssure support.
