How to expand a virtual disk in a storage pool on Windows server

Question

I initialy created a storage pool (named VMsData) of 1.63 TB with two raid disks of 838 GB each.

In this pool I created a virtual disk (VMsDisk1) using the full capcity of the pool.

Later to get more disk space, I added a third raid disk of 838 GB and added it to the existing storage pool VMsData, expanding it's capaciti to 2.45 TB.

My problem is: I don't know how to expand the virtual disk VMsDisk1 with the existing free space in the storage pool.

This screenshot shows the state of my storage, and my goal is to have VMsDisk1 allocated 2.45 TB.

I hope somebody can help.

Hi sivi1 nesivi1,

Hope you're doing well.

Please open PowerShell as an administrator and input the following command to check NumberOfColumns:

**get-virtualdisk -friendlyname diskname | fl ***

If we use two physical disks to create the "StoragePool", the "NumberOfColumns" of the "StoragePool" will be 2. If we want to extend the "Storage Pool" or "Virtual Disk", we must add 2 or a multiple of 2 the same size disks.

Please note that we must ensure there is data backup in place.

Best Regards,

Ian Xue
