Snapshot Manager shows no open snapshots but VM's directory shows delta files.
Check the timestamps of the files within the VM's directory. The delta files should have a newer timestamp.
Run cat or vi on the vmx and vmdk header files. The vmx should be pointing to the vm's file. The vmdk's should be pointing to the delta files.
Run the following.
vmware-cmd vmfs/volume/vmfslabel/VMName/VMName.vmx hassnapshot
If a snapshot is found and you want to commmit it run:
vmware-cmd vmfs/volume/vmfslabel/VMName/VMName.vmx removesnapshots
If hassnapshot or removesnapshots shows no snapshots or fails to remove snapshots, create a new snapshot through the VIC.
If you are able to create a snapshot, go into the Snapshot Manager, select the new snapshot and then choose to Delete All.
You should be able to see the timestamp on the vm's vmdk files updated as the snaps are commited.
