We have a VM called ISTQB, yesterday morning it was noticed that this was offline. On investigation we found that the VM had a 'consolidation needed' message. I performed the consolidation which failed. On investigation of the Datastore within which the VM resided we found CTK.VMDK files for each of the HDDs. After doing some research I removed the CTK.VMDK files and managed to power up the VM. We would now like to find out how this happened?. The problems seemed to begin at around 07:06 on 25/06/2014.
Can anyone explain or share your views on this.
