I have a VM that returns the error "The operation is not allowed in the current state." when i try to either take a snapshot or expand a Thin-provisioned disk or make any other changes.
VM tools are up to date on the VM and the issue only occurs for this VM other VMs on the Host and in the cluster are able to take snapshots and have hardware modified. I happened upon this issue since i need to update the VM and was attempting to take a snapshot in case the update went wrong.
I have not been able to find a cause for this error, but I have found the following abnormalities:
- The VM show it has no snapshots but looking on the LUN it disk resides on it appears to have four deltas ie VMName0004.vmdk
- there is plenty of space on that LUN and it is not overprovisioned.
- The VM is server 2012 and the vmtools service is running but when i attempt to migrate the VM to another host it shows the following warning. But there are no alarms at the VMlevel
- "No guest OS heartbeats are being received. Either the guest OS is not responding or VMware Tools is not configured correctly."
- The VM itself is running fine without any abnormalities.
I can access the Logs for both the VCSA Virtual appliance and the host that the VM appears to be stuck on but i have no idea what log to start with. I have been blindly search around with no luck.
