Hi,
at first:
I had for this special situation already a Case with VMware. But without satisfactory result...
I*m running VMware ESXi 5 and vCenter 5 (both latest Build), under some special condition a Snapshot with VSS Fails with the following error:
'VssSyncStart' operation failed: Unbekannter Fehler (0x80004005)
-> unkown error
There is no visible in-guest Error (eventlog, vssadmin list writers). The eventlog looks like the snapshot is complete successful...
Snapshot without VSS works great (with Sync Driver or without quiescence).
I also tried reboot of the VM, re-install VMware Tools, tried VSS in the Guest.
It`s an VM with 2 Disks, both vmdk,1 SAS controller for first Disk, 1 PVSCSI for Data Disk.
OS: Windows 2008
App: vCenter incl. SQL Express
After this error occurs the VM is running on a Snapshot, bit the Snapshot is not visible in the SnapShot Manager:
And now two questions:
- does anyone have the same VSS problem?
- does anyone have the same orphaned snapshot problem?
In the attachment is the vmware.log of the VM with vss and backup debug enabled.
