Snapshots cannot be committed.Snapshot commits without errors and Snapshot Manager is no longer populated. However, the snapshot disk is present in the virtual machine directory. (the VM is still running on Snapshot) Consolidation failed with the errors similar to: Failed to lock the file or One or more disks are busy. or Unable to consolidate virtual machine snapshots due to file lock. or Unable to access file since it is locked. The virtual machine summary tab display messages similar to: snapshot consolidation required. or Virtual machine disks consolidation is needed. or Virtual machine Consolidation Needed status. Note: For additional symptoms and log entries, see the Related Information section.
Virtual Machine file lock have multiple reasons. This article covers the file lock caused by backup application proxy virtual machine.For more information about Virtual Machine file lock, see Investigating virtual machine file locks on ESXi hosts (10051).
This issue occurs if the backup proxy virtual machine or other virtual machine holds a lock on the base disk or previous snapshot file of the virtual machine that has the consolidation issue, preventing the snapshot consolidation to succeed.
To resolve this issue, remove the virtual machine disk(s) from backup proxy VM.Caution: Make sure there is no backup job running on the virtual machine that has the consolidation issue. Right-click the backup proxy virtual machine.Click Edit Settings.Expand all the Hard Disk(s).Select the Hard Disk(s) which belong to the virtual machine that has the problem.Click on the X beside the Hard Disk to unmount the Hard Disk from the VM. Caution: Do NOT select Delete files from the datastore. Click OK.Consolidate/Delete the snapshot on the VM.
