Symptoms

Creating a Virtual Machine snapshot in vSphere fails with the below error:

"Operation failed!

Status: Unable to access file snapshot "

vCenter Snapshot failure message

An attempt to migrate the VM to another host did not resolve the issue. It caused a failure to power the VM back on and reported "insufficient resources" as the error.

A review of the following confirmed that there was not a resource issue:

  • Volume size on the PowerStore
  • Datastore size in vSphere
  • vSphere HA settings
  • Virtual Machine CPU and RAM 

Cause

Many issues can contribute to snapshot creation failures such as file locks, lack of space, and so forth. In this case, the underlying cause for the snapshot creation failure and the failure to power back on after a migration attempt, could not be determined.

Resolution

The issue was resolved by creating a new virtual machine with the same name and pointing it to the original VMDK files, then deleting the old virtual machine.
