When Windows prompts we are running low disk space on one RAID 5 partition, now we need to increase RAID 5 partition size in some way. Is it possible to take spare space from other partition to extend the partition? If so, how will we deal with it?

The answer is “Yes”. We know that RAID 5 generally combines three or more disks in a way to protect data against any single disk and is becoming the most frequently-used RAID array for data storage because of the self-correct ability. And RAID 5 partition on Windows Server is able to help administrators for better data storage and hard disk management. But there are still some problems we need to resolve and the typical matter is to increase RAID 5 partition size, especially the system partition.

Obviously, a third-party server partition manager such as MiniTool Partition Wizard which offers quite workable solution for partition extending is really needed.
