Is it a Gluster cluster?

Because I have a gluster volume on CentOS7 cluster is not possible to change compatibility level, else if I have all hosts in maintenance mode

I confirm: I am not able to modify compatibility level using engine UI. I'm running oVirt Version 3.6.7.5-1.el7.centos and I would upgrade to 4.0 I was able to migrate HostedEngine to Default Cluster On one of the clusters (CentOS7 cluster) I can't change Compatibility level from 3.5 to 3.6 value Now the problem is that I have a gluster volume. If I delete Gluster Volume from HE UI can I loss data?
Deleting gluster volume from UI will delete the underlying volume if any of the hosts in the cluster are online - i.e it's not a database entry deletion alone, it executes gluster cli command to delete the volume.
Why do you want to delete the volume? Is it to move the hosts to another cluster/ change compatibility? Which cluster has the gluster volume - CentOS7 cluster or Default cluster?

You can also put all HE hosts on that cluster to local maintenance and shutdown the vm. It will start up on another cluster.

For some reason it is not possible migration of he vm to another cluster. This is the reason I asked for direct DB modification. Fedele
You can live migrate the he vm cross cluster and then upgrade the compatibility level. Yaniv Dary Technical Product Manager Red Hat Israel Ltd. 34 Jerusalem Road Building A, 4th floor Ra'anana, Israel 4350109 Tel : +972 (9) 7692306 8272306 Email: ydary@redhat.com IRC : ydary

As I wrote this morning using a smartphone: I can't change compatibility using UI engine because the HE is running. For this reason I need to change the compatibility value in the DB. The problem is that in oVirt 3.6 I can't find any cluster named table as described in Comment 17 of https://bugzilla.redhat.com/show_bug.cgi?id=1341023 Can anyone verify? Thank you Fedele
