When i delete the snap shot in snapshot manager in Vsphere client, I get remove snapshot request time out


We have VMware Vsphere Client 5.5.0 and  the space on Exchange only 27Gb. All I want is to the expand the D drive.
When I right click the VM  and edit settings and click Hard disk 1 , Disk provisioning is completely greyed.

I came across an article which said , if it is greyed , that means the snapshot  is in progress. I went to the VEEAM back up server and noticed that no Exchange backup is running.

I right clicked the VM- snapshot-snapshot manager and noticed that 2 VEEAM BACKUP TEMPORARY SNAPSHOT  listed there.

I selected the bottom snapshot and clicked delete and it was saying snapshot removal in progress. After some time it throws and error
"remove snapshot request time out"

Please suggest , what to do at this stage  and is there a safe way of removing these snapshot. Please see the attached  the snapshot manager.

Okay, there are a few things you need to check, it is correct you *CANNOT* increase a virtual hard disk, if you have a snapshot, it must be removed first.

and removal of a snapshot, needs to be done with caution, this depends on why you have a snapshot, and this is cause Veeam has left your VM running on a snapshot, size of the snapshot, and storage space left on the datastore.

27GB is not a lot of storage space, also be aware that snapshots grow, approx 1GB per hour, on an idle machine, and get larger, when there is no more space on the datastore, the VM will fail, and could cause virtual disk corruption.

HOW TO: VMware Snapshots :- Be Patient

So can you screenshot the VM folder, so I can have a look at the sizes of the snapshots.

You may have to shutdown the VM, and handle the snapshots (and that does not mean, manually delete them from the datastore)

I can work with you to resolve this issue.
