You plan to extend the volume by adding an additional 3 TB.
What is the minimum amount of extra disk capacity required to accommodate extending the volume?

  • A. 3TB on the coordinator node
  • B. 3 TB per node
  • C. 4 TB per node
  • D. 4 TB on the coordinator node

In a cluster with 3 servers, the default disk layout is 3-way mirror. That means a 3TB increase should cost you 9TB footprint increase, or 3TB per node. If you just add 3TB hard drive, you won't get an additional 3TB in your S2D volume.

Millie, I made a mistake. You are correct and the answer is B, and here is why Supported: different sizes across servers The first two servers use 4 TB HDD but the third server uses very similar 6 TB HDD. Server 1 Server 2 Server 3 2 x 800 GB NVMe (cache) 2 x 800 GB NVMe (cache) 2 x 800 GB NVMe (cache) 4 x 4 TB HDD (capacity) 4 x 4 TB HDD (capacity) 4 x 6 TB HDD (capacity) This is supported, although it will result in stranded capacity.

Correct answer is B. https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/resize-volumes Capacity in the storage pool Before you resize a volume, make sure you have enough capacity in the storage pool to accommodate its new, larger footprint. For example, when resizing a three-way mirror volume from 1 TB to 2 TB, its footprint would grow from 3 TB to 6 TB. For the resize to succeed, you would need at least (6 - 3) = 3 TB of available capacity in the storage pool.

I guess correct answer is B. https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/drive-symmetry-considerations "Same drive sizes in every serve: Recommended" So, if extend by 3TB, all other nodes can have additional 3TB.

Millie, I found this in your reference, according this article the answer is A. Sizes: We recommend using drives of the same sizes whenever possible. Using capacity drives of different sizes may result in some unusable capacity, and using cache drives of different sizes may not improve cache performance. See the next section for details.
