Extend volume greyed out in Server 2012 Disk Management
Generally speaking, we can take advantage of the “Extend Volume” feature provided by the Server built-in Disk Management. However, in most cases, you might find the “Extend Volume” is greyed out and not clickable. That’s because “Extend Volume” only can be used with contiguous unallocated space at the right side of the system partition or other partition you wish to enlarge.
If there is no unallocated space, space, we can shrink one existing partition to get, but “Shrink Volume” can only free up space behind the partition we shrink, while moving partition is not supported by Disk Management. To extend system partition Windows 2012 successfully, deleting the partition behind system partition to get an adjacent unallocated space is the only way we can do in Disk Management. It is at the risk of losing data.
