Hi,
If I create a second Cluster on the Data Center, can I share the same 
Glusterfs storage with the Hosts on the different Clusters?
When creating a second cluster do I need to select "Import existing 
gluster configuration" and than "Enter the details of any server in the 
cluster", the details are about the Gluster storage server?

If you're already managing the gluster nodes in another cluster, there's 
no need to add it again. I'm not sure I understand the setup. You need 
to enable gluster services in the second cluster only if this is going 
to have gluster volumes running on it. To use a gluster volume (running 
on another cluster), there's no need to enable gluster service.

Thanks

Hi Moti,
Thanks a lot. Do you think we lost functionalities? like server migration?
The other way should be creating a new cluster, configure the old 
hosts on this new cluster. Is possible to share the same GlusterFS 
storage between 2 clusters? Is possible to migrate servers and disks 
between the 2 clusters?
Regards
José

Hi Jose,
The correct way to do it is by:
1. Putting all hosts in maintenance mode
2. Changing the cluster cpu type to the desired one
3. Install the new host
4. Activate the hosts
5. Re-run the vms

Hi,
     I'm trying to add a new old host (Intel(R) Xeon(R) CPU  X3430  @
    2.40GHz Intel Nehalem Family) to oVirt Engine Version:
    3.5.4.2-1.el7.centos.
    But I'm getting this error:
    host does not meet the cluster's minimum CPU level. Missing CPU
    features : model_SandyBridge
What happen if I lower the cluster CPU type? Do I loose
    functionalities? Do I need to shutdown all VMs before change the
    cluster CPU type?
    Do you see any problem here?
Thanks
José
