Failover Cluster Manager incorrect volume size

Hello, I have a server 2012 R2 with Failover Cluster Manager setup. We also have a Dell Compellent. I recently expanded the storage via the Compellent and then extended storage in Disk Management. In Disk Management the new size looks correct but it hasn't updated in Failover Cluster Manager; it still shows old volume size. A few of out VMs have paused because we're low on space. How can I get Failover Cluster Manager to show updated space?

I did some online research but nothing has helped.

On one of the server nodes please run the following in an elevated PowerShell:

Get-PhysicalDisk
Get-VirtualDisk
Get-Disk

Open in new window

Please publish the results either via attached TXT or in a CODE snippet.

Hi sorry for late reply. Was OOO on Friday. Please see screenshot.

In an elevated PowerShell on all nodes run the following _twice_:

Update-StorageProviderCache -DiscoveryLevel Full

Open in new window

Make sure FCM is closed prior to the above. Then:

Get-PhysicalDisk
Get-Disk
Get-ClusterSharedVolume
Get-ClusterSharedVolumeState

Open in new window

Just ran those commands but still the same issue.

Pause and drain then reboot each node one at a time. Do they pick-up the additional storage?

Drained roles and rebooted. Still not picking up additional storage.
