You can get unallocated space by either shrinking or deleting a partition, and merge unallocated space to other partitions on the same disk easily with NIUBI. However, in some servers all partitions on the disk are almost full. Some people are wondering whether it is possible to merge unallocated space to a different disk, the answer is no. Because the size of a physical disk is fixed, a 500GB disk can't be reduced to 300GB or increased to 700GB.
In this situation, you may move a partition from the full disk to another one, then delete this partition and add unallocated space to other partition. Another method is copying this disk to a larger one, extra disk space will be shown as unallocated at the end of disk. Then you can merge the unallocated space to other partition(s).
