Since upgrading our ESXI environment from 5.1 to 5.5(including building new VCenter servers), we have noticed that our "provisioned" storage on some of our datastores are now showing as double the size of the actual VMs on that datastore.
For example, In one of my datastores, I show a provisioned size of 1.65TB. This datastore only has 1 VM on it with 2 disks. The first disk is a Thin provisioned 50GB disk. The second is a Thin provisioned 830GB disk.
We originally provisioned the datastore to be 1TB. There are no active snapshots for this VM and his has been confirmed both in the datastore view as well as a visit to the command line using SSH.
In my open ticket with VMWare, the tech tried to tell me that we just over-provisioned our datastores but this is not true. We know what size we provisioned them...VSphere is showing that size as different now and we would like to resolve this.
On the summary tab of the datastore, we see the following:
Provisioned Space: 1.65TB
Free Space: 216.37GB
There are no snapshots at all. The VM has 4GB RAM. It has a total of 880GB disk space(although all of it is not being used)
Any ideas while I wait for VMware? Our ticket is still open while we do research. Taking the VM offline(removing from inventory and re-adding) is not an option as it is a production VM(File Shares) and it is used all day every day. Please help.
