I would still be interested in knowing what the relationship between DHCP and the VSS service are, if the install of DHCP is incorrectly applying some settings or creating an association somewhere in error, and is potentially known and being worked on for a fix.
VSS ProvidersCheck to see if there are any non-standard providers that are causing the problem when performing the VSS snapshot. To do this, go to the command-line and execute the following command "vssadmin list providers".
That should fix the VSS Writer problem. Also, as a side note, when your SqlServerWriter dies, you can re-set it by going into services and restarting the Sql Server Vss Writer service. This avoids having to re-boot every time you want to reset the VSS SqlServerWriter. Many thanks to Microsoft support for helping with this issue...
Now though, when I attempt a VSS snapshot and that VM happens to be running, I get the VSS_WS_FAILED_AT_FREEZE error. If that VM is not running, the VSS snapshot works fine.
The VSS service is shutting down due to idle timeout. I checked the VVS service and this was set to Manual (which is correct) however this was not started... Do you have any more ideas on this problem, help would be appriciated..?
SO, make a separate LUN and give the volume using VSS a nice reasonable amount of thick storage for your needs. Only use thin if you are short on storage in the short term.
Use Production Checkpoints for applications which are VSS-aware. It might be easier to identify the issues if we would know what kind of applications you are running on the virtual machines (VMs).
Please check that the Event Service, the VSS service and the shadow copy provider service is running, and check for errors associated with these services in the Application Event Log on the server ediadb2.commercedesk.com.
In dpm 2010 with the latest patches and running on x64, i have it set to backup the intial store and one child partition from a hyperV VM.. both are failing with the following:
The VMs that appear to have the issue have Oracle installed and the one I have the severest problem with doesn't have the Oracle VSS Writer installed. I have stopped all the Oracle services on the VM but still get the VSS Writer failures. I have now raised a call with Microsoft so will update any useful info afterwards.
