Windows Server 2016 With Storage Spaces Direct:
My first CSV is a 2-way Mirror that I want to remove. I have used "Move Virtual Machine Storage" to emtpy Clusterstorage\volume1". All VMs are running OK on another CSVs now. However there is 1 file left on volume1: \Hyper-V\shared\Groups\groupregistry.vmcx. The file cannot be deleted. The cluster looks OK if I set the CSV to offline and remove the file, but before I removed the CSV i noticed that VM migration between nodes did not work. As soon as the CSV was enabled again everything went back to normal, and a new file groupregistry.vmcx was created.
Is the cluster dependent on volume1, or is this configurable? How can I get this disk removed and replaced? Or can the disk be reconfigured as a 3-way Mirror or Parity?
