For the System Center VMM VM Placement the Virtual Machine Manager 2012 R2 takes the larges Volume from the Cluster it will find.
BUT I have a very large SATA Volume presented to my Cluster, i do not want VMs places to that Volume.
Sorry, my Azure Pack is doing that, not the VMM.
the original syntax is:
fsutil file createnew filename length
I invoked this command for creation of a 500Gb:
fsutil file createnew c:\ClusterSharedVolume\Disk2\test.txt 50000000000
here is the original bolg post i found in the net:
