Andy's VMware vSphere tip#7: SNAPSHOTS (Hyper-V calls them Checkpoints!) Believe it or not one of EE most asked questions in the VMware Topic area, at least one question a week is asked in the VMware Topic, and the response by many VMware Administrators, is "my datastore has filled up, my VM has stopped working, and says retry or abort - I've checked and there are no snapshots reported in Snapshot Manager!"
I'll tell you it It lies to you.... quickly check VM Folder on the datastore, if you see a file -0000x.vmdk - the likelihood is you have a snapshot!
If you find yourself with a snapshot issue, out of your depth STOP! do not ignore it Ask for help on EE in the VMware Topic area, it's serious, and corruption can occur if not dealt with promptly and correctly.
