Yes, we've seen this snapshot issue.

screenshot of VM folder and files please.

Is this a VDI client or server ?

VM-FolderFiles1.pngIt is a Server.

Because I'm pretty new with this, how do I get in to the VM folders and files in order to take a screen print.

Let me know if the attached is what you needed?

I think you needed also the folder listing.

I see there is both a wlldocsql and a wlldocsqlTEMP wich the VM server is the wlldcosql.VM-FolderFiles2.png

there are no snapshots, that I can see.

what operation is trying to be performed, when the error occurs ?

I assume the VM is currently powered up?

However, when I look at the VM Server_replica, I see a Configuration Issue and it says Virtural machine disks consolidation is needed..

Can I consolidate the replica and still have the users attached to VM Server?

this is a replica, operations cannot be completed on a replica, because it's synced with the Parent VM!

what are you trying to do on the replica!?

Yes, it's a replica of a production VM, from VMware Replication or Veeam Backup and replication.

do you have a production VM which is currently on....called this?

Leave alone... or you will break the replica link between Parent and Replica!

so this is a replication job error ?

sorry, I misread.....

this is when the job runs.

Okay, have any changes been made to the original parent VMDK ?

e.g. has someone changed it's disk size, because this has broken replication.

see here

Resizing virtual machine disk files that are protected by vSphere Replication (VR) using VMware vCenter Site Recovery Manager (2042790)

or complete a Full Sync.

Andrew Hancock,

I tried what your recommended, but now I'm getting the following error when I try to power on the VM:

An error was received from the ESX host while powering on VM wlldocsql.
Cannot open the disk '/vmfs/volumes/51af4020-b48a54e4-5068-a0369f1d557c/wlldocsql/wlldocsql.vmdk' or one of the snapshot disks it depends on.

Now I'm stuck.  Do you know how I can fix this?
The file specified is not a virtual disk

possible the VMDK is corrupted, can you check if the VM is running on a snapshot disk.

see my EE Article for guidance

Last Night I ended up Recreating the VM Descriptor file.  That allowed me to power on my VM, but I still have the original problem.

While trying to follow your advice, I got stuck at cloning the VM.  I didn't have enough space in my datastore to complete the cloning.
