RAID 5 is a kind of storage solution integrating storage property, data security and low storage cost. Configuring RAID 5 demands at least 3 disks. RAID 5 doesn’t back up data but stores data and the corresponding parity check information to each disk. When data in one disk of RAID 5 are damaged, we can use the remained data and the parity check information to restore the damaged data. That’s why RAID 5 has higher security. The right picture shows RAID 5 disk array.
Since RAID 5 is compromising in many aspects, many servers adopt RAID 5 volume to store data files. And server users can also create RAID 5 volume with system’s built-in disk management tool. But what is annoying users is how to resize RAID 5 volume after it is created in Windows Server 2003. When needing to resize RAID 5 volume, users have to resort to the partition magic which is different from common partition management software that is only able to manage basic disk and partitions and can not manage RAID 5 and other dynamic volumes. This partition magic is capable of resizing RAID 5 volume. Then we’ll show how to resize RAID 5 with partition magic in detail.
Resizing RAID 5
Before resizing RAID 5, we need to visit http://www.partitionmagic.biz to download the partition magic. After installing it, launch it and we’ll see the following interface.
After the partition magic software is launched, we can see current disk status and distribution condition of dynamic volumes from its main interface. Select the RAID 5 volume that will be resized and click “Move/Resize” button.
This is the interface of resizing RAID 5. Drag the two triangles to resize RAID 5 volume, as follows.
After the adjustment, click “OK” to go back to the main interface to preview resizing effect.
After going back to the main interface, we can see the original RAID 5 volume has been resized, but the operation has not been realized yet. We also need to click “Apply” to perform it, finishing resizing RAID 5 in a real sense.
Through so simple operations, we easily resized RAID 5 volume. Do you also feel it miraculous? Actually, besides resizing volume, this partition magic is also equipped with other dynamic volume management functions which are shown in the left “Operations” action panel, allowing uses to manage dynamic volumes magically. More than that, this partition magic also has a lot of functions to manage partitions in basic disk.
