I was able to migrate HostedEngine to Default Cluster<br>
On one of the clusters (CentOS7 cluster) I can't change Compatibility<br>

If I delete Gluster Volume from HE UI can I loss data?<br></blockquote><div><br><br></div><div>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.<br><br></div><div>Why do you want to delete the volume?
