Snapshot or No Snapshot

I have a customer with a strange vmdk file. He deleted all snapshots but it still looks like there is one when you look at the datastore however there is no parent vmdk file. Even though this looks like a snapshot file could it in fact be just a standard vmdk file? See screen shot.

Thank you...

You can try to consolidate the files (see screenshot)
You can also see what disk file the vm is using currently (see other screenshot)

It is definitely a snapshot file. Can you consolidate again to make sure snapshots are committed?
That is if the data is needed. And make sure you have enough space before you consolidate.

Thank you for your replies.
It is using the 00005 file. I will try the consolidation option after the backup this evening. But if this is a Snapshot file where is the parent vmdk? The screen shot is the whole datastore for this VM.

@Rick

see my EE Article to confirm the disk is on a Snapshot..

HOW TO: VMware Snapshots :- Be Patient

and then, I would not bother with consolidate, it's a poor effort and fixing an issue.

1. Create a new Snapshot
2. Wait 60 seconds
3. DELETE ALL the Snapshots in Snapshot Manager.

Wait, Be Patient, and re-check is the VM disk still running on a snapshot if so...

we can use the CLONE operation to get rid of the snapshot.

The clone operation was going to be my last resort but looks like that is going to be what I need to do. Thanks!!

You can either use the CLONE option from the menu (right CLICK VM - CLONE), or use the command line, and use vmkstools, to create a new parent vmdk.

We've used this successfully on a VM with 72 snapshots....(and VMware, says, the VM fails at 29 snapshots!)

vmkfstools -i <most recent snapshot file name> /vmfs/volumes/<temp folder name>/<newfilename.vmdk>

I will most likely just clone it through vCenter.
Do you have any idea what happened to the parent or main vmdk file?

It must be around somewhere, otherwise the VM would fail to power on.

You'll find out, if the clone fails, if no parent exists!

A VM cannot exist in a snapshot alone, as it's chained to the parent.

No problems, CLONE always gets you out of a Snapshot issue, if stuck!

It's also the VMware Support solution for multiple snapshots, rather than Deleting them all!
