Hi All,
I am having serious problems with our production DPM server.The protected server that is having problems is a physical Domain Controller (DC1) with SCVMM installed (so SQL is also installed on it). Recently DPM has failed to create recovery points, and constantly reports the replica is inconsistent on 3 SQL Data and the VMM Backup Component. (VMM Express Writer).
I have been trying to troubleshoot this for a number of days now and its not been successful.
DPM Typically reports the following errors -:
The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: VssError:A writer did not respond to a GatherWriterStatus call. The writer may either have terminatedor it may be stuck. Check the System and Application event logs for more information.(0x80042319))
The target server DC1 logs error messages like the following.
The COM+ Event System failed to fire the PostSnapshot method on event class {FAF53CC4-BD73-4E36-83F1-2B23F46E513E} for publisher and subscriber . The display name of the subscription is "{75470F40-3413-4F68-BDBB-0443A6277674}". The HRESULT was 80042318.
The COM+ Event System failed to fire the Thaw method on event class {FAF53CC4-BD73-4E36-83F1-2B23F46E513E} for publisher and subscriber . The display name of the subscription is "{75470F40-3413-4F68-BDBB-0443A6277674}". The HRESULT was 80042318.
The COM+ Event System failed to fire the RequestWriterInfo method on event class {FAF53CC4-BD73-4E36-83F1-2B23F46E513E} for publisher and subscriber . The display name of the subscription is "{75470F40-3413-4F68-BDBB-0443A6277674}". The HRESULT was 80042318.
An unhandled exception was encountered while processing a VSS writer event callback method. The VSS writer infrastructure is in an unstable state. Restart the service or application that hosts the writer.
I have tried quite a few things from google and technet and peoples blogs etc to no success, so rather than speculate further or pollute the thought process anymore - I think a best approach to clear my mind and get other people thoughts and possible solutions and guidance - Any help in this matter is most welcome.
Kind Regards
Wayne
