It would really be best to not use snapshots as a permanent items. For a more permanent solution use templates. Snapshots should be something that you use, and then revert or delete.

What are those snapshots? Are they from VCB or others you had existing prior to running VCB?

They are from snapshots made in the gui as a couple worked after I wen

into the VI client deleted all snapshot then it worked. Do you know if

this behavior is by design or a bug?

ls

engrcpas-000001-delta.vmdk engrcpas-000003.vmdk engrcpas.nvram engrcpas.vmdk vmware-38.log vmware.log

engrcpas-000001.vmdk engrcpas-000005-delta.vmdk engrcpas-Snapshot11.vmsn engrcpas.vmsd vmware-39.log

engrcpas-000002-delta.vmdk engrcpas-000005.vmdk engrcpas-Snapshot1.vmsn engrcpas.vmx vmware-40.log

engrcpas-000002.vmdk engrcpas-8c45a923.vswp engrcpas-Snapshot2.vmsn engrcpas.vmxf vmware-41.log

engrcpas-000003-delta.vmdk engrcpas-flat.vmdk engrcpas-Snapshot3.vmsn vmware-37.log vmware-42.log

Here is what I get:

But why is the log file complaining about a snapshot called "VCB-BACKUP"? check the description/name in the snapshot manager....

Are you sure there is no VCB snapshot from a previous mount, perhaps that was never unmounted? Could be an orphan as well...
