<div dir="ltr">Hi<div><br></div><div>With the new multi-system ds functionality, it is now required that system ds is also part of the cluster. So, a VM will be deployed using any of the system DS in the cluster. In general, this requirement prevents wrong scheduling configurations.</div>

<br>
After upgrading from 4.2 to 4.4 an attempt to deploy a new VM fails with the error:<br>
<br>
FAILURE [VirtualMachineDeploy] cluster [100] does not have any datastore of type SYSTEM_DS<br>
<br>
The system DS 0 is not assigned to a cluster (anymore, I'm not sure). Trying to assign it to the cluster 100 leads to the error:<br>
<br>
FAILURE [ClusterAddDatastore] Cannot add object to cluster. Datastore 0 cannot be added to any cluster<br>
<br>
Is it not possible anymore to use DS 0 on a cluster? Do I have to create a new system DS? And if yes, how can I migrate the VMs saved in DS 0 to the new DS?<br>
<br>
Cheers,<br>
Tobias<br>
