Hi Roberto,<br>
<br>
Thanks for your information but....<br>
When I'm writing about DC I mean defined DC in oVirt and so far I
could see that when you define a storage domain in one oVirt DC it
will not be available in another DC and I don't know what would
happen if I would import it on the second DC.<br>
In your setup, did you just define 1 DC and multiple clusters?<br>
<br>
Regards,<br>

<div>Hi</div>
<div>I have in production the scenery
something similar to what you've described.</div>
<div>The "enabling factor" is represented
by an "storage virtualization" set of appliances, that maintain
mirrored logical volume over fc physical volumes across two
distinct datacenters, while giving rw simultaneus access to
cluster hypervisors split between datacenters, that run the VMs.</div>
<div><br>
</div>
<div>So: cluster also is spread across dc,
no need to import nothing.</div>

<span>Is it possible to have a shared Storage domain between 2
Datacenter in oVirt?</span><br>
<span>We do replicate a FC Volume between 2 datacenter using
FC SAN storage technology and we have an oVirt cluster on
each site defined in separate DCs. The idea behind this is
to setup a DR site and also balance the load between each
site.</span><br>
<span>What happens if I do import a storage domain already
