    Hey...I just noticed something.
    
    I have a datastore that I manually added to my ESXi hosts (shared storage) that is based
on an iSCSI target.
    
    When I restart the CS MS, this datastore (which I already added to CloudStack as shared
primary storage) gets re-added as local storage (so it's listed as both shared and local primary
storages).
    
    I think this is perhaps what lead to this pull-request in the first place, but the problem
still exists.
    
    What happens now that this pull-request code is in is that the datastore conflict is detected
and an error message is printed, but I still see my shared primary storage has been added
as well as local storage.
    
    I'm looking into this more, but wanted to point out this observation.
    
    I had forgotten about this issue (I think it's pretty old). At the time, we put in a workaround
where datastores that started with "-" or "_" were assumed to be shared and not re-added as
local. It just happens that my manually added, shared datastore does not start with "-" or
"_", so I see the problem.

> During host discovery, if local storage is enabled for a zone, all VMFS datastores that
are mounted on just one host (i.e. not shared) will be added as local storage is CloudStack.
> When admin adds a VMFS datastore as shared, CS doesn't verify if the storage has already
been added as local storage in the zone. This means the same primary storage is added as different
storages in CS and this leads to failure in operations related to disks because of wrong storage
look ups.
