Can't share ISO file instead of copying it

Hello.
I have the last VMM 4.0.2244.0.

I have three nodes in failover cluster: srv-hv-00[123]. This cluster has two roles: hyper-v and file server. Also this cluster has two clustered MPIO storages: one for hyper-v role with machines and the second storage for high availability VMM library. This VMM library has only ISO and templates of VMs.

The hyper-v cluster name is hyper-v-cl-001.XYZ.
The file server clustered role has name hyper-v-lib-001.XYZ.
All permissions are set correctly to share file instead of copying it. I tested it.

Lets imagine two situations:

1) The VM is hosted on the first node cluster - srv-hv-001. The owner of clustered file server role is the third node - srv-hv-003. In this situation I can share ISO file instead of copying it.

2) The VM is hosted on the first node cluster - srv-hv-001. The owner of clustered file server role is the first node too - srv-hv-001. In this situation I can't share ISO file instead of copying it and get the usual error: 

Error (12700)
VMM cannot complete the host operation on the 'srv-hv-002.XYZ' server because of the error: 'test' failed to add device 'Virtual CD/DVD Disk'. (Virtual machine ID 47F528E6-3E9B-4A32-8461-3399F6411A7E)

Recommended Action
Resolve the host issue and then try the operation again.
