Error extending virtual disk in storage pools RRS feed

  • Question

  • Hi, I tried to search around for anyone else with this problem but couldn't find anything, so I thought i'd post.

    We have a 2016 server set up in EC2 as a backup repository, with 8TB of disk space.
    I'd like to increase it to 16TB in size, so I've added the disks (HDD and SSD) and am trying to now extend the virtual disk. When I extend it to 16TB, it fails after about 10 seconds with the message, "Error extending virtual disk: Not Supported. Activity ID: {4a66cb30-7b9c-4a68-88c5-3c9071f48008}".

    Just to check off the steps, I have:

    - Added the disks themselves
    - Brought them online and initialized in disk management so they appear in "Physical Disks" in Server Manager -> Volumes -> Storage Pools
    - Set the MediaType to HDD/SSD for each disk

    Can anyone suggest why this error is coming up, or let me know if I might be doing anything wrong? Thanks for your time.

  • I know with Server 2012 R2 you need to use the required amount of disks to extend the space. I haven't had the chance to play around with Server 2016 Storage Spaces yet but check this blog post:

  • Thanks, it seems like my NumberOfColumns is set to 0.

    Not sure how that happened, but I'll see if I can either change that to 1, or just create a new virtual disk configured correctly and copy everything across.

  • Hello! I also encountered this problem, that I counld not extend a storage tiers. The  parameter NumberOfColumns is 0. 

    So do you fixed this problem?

    Thank you.
