I'm also puzzled by this statement: "A local storage domain can be set
up on a host. When you set up host to use local storage, the host
automatically gets added to a new data center and cluster that no other
hosts can be added to. Multiple host clusters require that all hosts
have access to all storage domains, which is not possible with local
storage. Virtual machines created in a single host cluster cannot be
migrated, fenced or scheduled. "
So .. let's say I have two nodes, both of them have some local disk, and
use the NFS data store. I can see why I wouldn't be able to migrate a
host from one node to the other IF that has was using local data storage
for the specific virtual machine. On the other hand, if it's a VM that
is NOT using local storage, and everything is in the NFS datastore, then
does this I can't migrate it because each host would have to be in its
own cluster only because it has local storage for *some* of the VMs!?
Each local storage host requires it's own datacenter and you can't mix a
datacenter with local storage with NFS storage.
sigh. This seems so rigid! I understand, for example, why clusters
must encompass same CPU type. I do not understand why a host cannot
connect to both local data storage, and NFS storage.
it's a legacy limitation we are working on eliminating
