I have an smvi job scheduled daily that fails. I have attached the error log. It looks like SMVI attempts to create the VMware snapshot and fails due to a protocol error from VMX. Doing a quick search on VMWare forums states its a problem with a custom quiescing scripts http://communities.vmware.com/message/1016429#1016429- is this a problem with SMVI's script to trigger the VMWare snapshot?
As a side note I can manually create the VMWare snapshot. Also to note there are three smvi snapshots already in snapshot manager that look like they have never been committed. I have attached the .bmp file that shows this. I imagine it could be the error is being thrown due to the existing smvi snapshots present. Then my question is why is smvi not committing these snapshots?
I have found a few threads on the VMWare community forums for the same issue (just with VCB/whatever else as the instigator) and the easiest solution is typically to just restart the vmware tools service in the guest.
Yes vmware tools is running on this virtual machine. The file system sync driver is installed and VSS is not installed. Uninstalling the sync driver and running the job again failed with same error. I then uninstalled vmware tools and powered off and on the virtual machine and the job ran successfully. So it looks like the sync driver was the issue although I am not sure why. I know it is responsilble for freezing and thawing the file system but what would cause it to fail?
It looks, sounds & smells like the very same problems we have faced recently during SMVI & SnapDrive 6.1 testing - so far support guys didn't come back with nothing more creative than "don't use the sync driver".
Apparently the bug sits on VMware side, so it's up to them to sort this out.
Most recently I received an error taking a snapshot of a virtual machine with the virtual machine memory option checked. The error was "A general system error occured: unable to save snapshot file." If I uncheck the snapshot the virtual machine memory option the snapshot works fine.
If you try a manual VMware snapshot, do not just right click on the VM to take a snapshot. Instead, go to the Scheduled Tasks page and create a new scheduled task to create a snapshot of the VM. Make sure you that check to enable disk consistency and turn off the memory snapshot. You can then schedule it to run just a single time. This will then mirror how SMVI creates a VMware snapshot.
