Hey Checkyourlogs Fans,

Today, I had a call from a customer that had a full volume on one of their AzureStack HCI 2-Node Clusters. They have a few volumes created CSV01,02,03, and they are all set up to use Nested Relisiency. I found that the documentation out there didn’t have a perfect example of how to do this for this scenario so here you go.

As you can see, CSV03 is down to 1 MB free, and this is causing our problem.

With the few steps below, you can see how I expanded this volume using existing pool free space.

First, let’s have a look at the Storage Tiers: Get-StorageTier

Now, Resize CSV03 – Get-StorageTier csv03* | Reize-StorageTier -size 1250GB -Verbose

Verify the change – Get-VirtualDisk

Expand the Parition –

# Choose virtual disk

$VirtualDisk = Get-VirtualDisk CSV03

# Get its partition

$Partition = $VirtualDisk | Get-Disk | Get-Partition | Where PartitionNumber -Eq 2

# Resize to its maximum supported size

$Partition | Resize-Partition -Size ($Partition | Get-PartitionSupportedSize).SizeMax

Instructions from: https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/resize-volumes

So just like that, we have expanded our Nested Resilient Volume in AzureStack HCI.
