How to Increase an Active Intel® VROC RAID Volume Size Using New, Bigger-Size Drives


Non-volatile memory express (NVMe) Solid-state drives (SSDs) Intel® Virtual RAID on CPU (Intel® VROC) in a redundant RAID array Intel Server Boards


Steps to maintain the current RAID array using new drives with a higher size capacity


Unable to increase the size of the RAID volume.
Unable to determine if the Intel VROC option called Increase Size would work.


If the goal is to replace all drives with a bigger capacity, proceed with the below two options:


Irrespective of the chosen option: Back up your data.

Option# 1 (By starting from scratch):

  1. Replace the drives.
  2. Re-create the array.
  3. Restore the data.


Option# 2 (if the system is in production):

  1. Replace one drive with a bigger drive and wait for the rebuild to finish.
  2. Repeat this previous step for each of the other drives.
  3. Use the Increase Size1 button next to the Volume Name from within the Intel® VROC Graphical user interface (GUI) to increase the RAID volume to fully utilize the new disk spaces.

The Increase Size button next to the Volume Name from within the Intel® VROC Graphical user interface (GUI) (see image 20 of the Intel® Virtual RAID on CPU Windows* Software User Guide) is solely if there is additional free space in the existing array. For example, you have 500 GB RAID 10 volume on 4x 1TB drives; you can then increase the volume using the "Increase Size" button to fully utilize the remaining 500 GB free space.


You might need to also use Windows* Disk Management to increase the partition size to fully utilize the expanded RAID volume.
