Sorry, I made a mistake. Wrong IP address of the glusterfs server on /etc/hosts.
Now I have the second host on the second cluster green.

I lower the cluster CPU type but a Windows 10 VM did not boot and I was not able to install a second host, with this error message:
Host node2 reports about one of the Active Storage Domains as Problematic.
The error message for connection gfs1:/ gv0 returned by VDSM was: Problem while trying to mount
Any help?

I tested and was not able to share the same gluster storage domain with 2 clusters
Any suggestions, on what is better to do when having hosts with different CPU level?
Thanks

Thanks,
Yes, my intention is to run hosts with a different CPU level (older) in the second cluster. I want to run hosts on this second cluster and VMs using the same Gluster storage allready installed on the data center. The Gluster Storage is used by the first cluster with a host running VMs.

I have the gluster storage already working on the first cluster.
So, when configure the second cluster, as I understand, I only need to Enable Gluster Service on the Cluster?
Your intention is to have hosts with a different CPU level (older) in the second cluster. And these hosts will be used to run VMs, IIUC. So you only need to Enable Virt service.
Regarding your question, on if the 2 clusters can share the same gluster storage domain - I don't know the answer to this.
Nir, Allon - is this supported?

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.

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
