Here are some typical examples.

  • I have a SBS2003 standard server. My system partition C: drive is run out of place on the created RAID 5? Do I need to recreate a RAID 5?
  • I have a Dell Poweredge 4300 that I setup using a RAID 5 config. The C: drive has little space left (<750Mb) and I would like to find something that can successfully expand partition raid 5 without losing data as this is a production server.
  • I have a Windows 2003 server with a single raid 5. System partition C is running out of space and low disk space warning jumped out. Is there any way to resize partition raid 5 without reformatting or loss data?
  • I added another 500GB drive to my raid 5 array and did an online expansion so I have space free now on the array. How do I just resize raid 5 partitions now to use this additional space? Any free tools?

Yes, the best solution under this condition is to resize RAID 5 to expand partition raid 5 instead of recreating.

Resize RAID 5 partition tips

Generally, RAID is configured with Windows Server, so to resize RAID 5 partition you need to take care. If system partition is out of space but there is free space on other partitions, you can simply shrink other virtual partitions and then extend the system partition with partition magic server.

If there is no free space on all virtual partition on the RAID 5, you have to add another disk to the RAID 5 array. After that the new disk space will be displayed as unallocated at the end of the virtual disk, and then you can resize partition with partition magic server.

Please note:

  1. Don’t break the RAID array if you need to resize partition RAID 5, just operate like resizing partition on physical hard disk.
  2. If you need to add new disk before resizing RAID 5 partition, you have to make sure the RAID controller has the feature to re-configure RAID without data losing.
  3. Backup the important files, as no partitioning software can guarantee the security 100%.
