I have two SAS raid-0 arrays on my workstation/test server. I usually keep data on array2 and OSs on array1.
Array1 has 3 OS installations since I am testing a few things using win8, hyperv2012 and win2012R2. I created the Win2012R2 volume with 80GB and left about 700GB for use by VMs but after installing the OS, the volume wizard does not show any space for the drive.
Volumes for the OS drive shows 100% allocated for 931GB but I know that there is only about 300GB that was partitioned including Win2012 so I am unsure how to release that space for use.
Disks shows that the OS is installed on a MBR partition on an 931GB SAS drive.
I have another drive in the system for the OS and a few attached backup drives to move the other OS installs in case I have to reformat array1.
Any suggestions on how to access and use the 700GB unused space on array1?
