I would upgrade my CentOS 6.8 to 7 on my cluster of 5 ovirt nodes (actually I'm running oVirt 3.5 and glusterfs 3.7). Anyone has experienced troubles for this upgrade?

ok, I understand you suggest to upgrade centos 6.8 to 7.2 first Correct?

You cannot upgrade ovirt on centos 6, since 3.5 is the last version supporting it. Best would be to upgrade the hypervisors to centos 7, which will pull latest ovirt anyway. > The ovirt-engine is hosted Upgrading the hosted engine vm is not related and more delicate, It should be possible using hosted engine setup. Adding Simone to add more info on that.

I misread your question - you seems to already run centos 6.8. I guess you are not using block storage (iSCSI/FC), do you?
