Hi Gents,

I've been using HyperV Core exclusively in my Home Lab since I started working for this company, I use 2 x HP Elite 8300 boxes for each HyperV host running from a removable USB Pen drive. Each box has 32GB of Ram and enough disk space to run VMs on local disks. 

Recently, I decided to play with clustering so I set up a third box (same Hardware as above, packed it with enough disks to add up to 4gb. I use Windows Server 2016 Datacenter edition in eval mode configured as an ISCSI target Server, I set up a 400gb drive as the Quorum disk and the rest I've carved off 2Tb for shared storage, both HyperV hosts can see the shared storage.

Both HyperV Hosts are now successfully clustered and have access to the shared storage above.

I want to move the VMs that are currently installed in each HyperV's local storage to the shared storage but I'm not able to do this, is it not achievable? am I trying to do something that isn't possible?

Hi,
what kind of errors are you getting? This should be easily doable.

I'm accomplishing this task by migrating the VM Storage to the Cluster Volume, I can only do this for one of the nodes in the cluster,  for some reason, the other node can't 'see' the same same volume, the said volume is showing up as 'reserved' and offline in disk management. When I try to bring it online, it comes up with the message, "the specified disk or volume is managed by the Microsft Failover Clustering component. The disk must be in a cluster maintenance mode and the cluster resource status must be online to perform this operation."

Obviously I shut down my lab machines at night, perhaps I'm not turning them on in the right order? should it be Cluster nodes first before Storage? or the other way round?

What you are seeing is correct. Only one host can actively access a shared disk, the other nodes use redirected I/O. You need to use Failover Cluster Manager and not Hyper-V Manager to do the move.
