Hello, my engine is 4.4.3.12-1.el8 and my 3 oVirt nodes (based on plain CentOS due to megaraid_sas kernel module needed) have been updated, bringing them to CentOS 8.3. But if I try to put cluster into 4.5 I get the error: " Error while executing action: Cannot change Cluster Compatibility Version to higher version when there are active Hosts with lower version. -Please move Host ov300, ov301, ov200 with lower version to maintenance first. " Do I have to wait until final 4.4.4 or what is the problem? Does 4.5 gives anything more apart the second number... (joking..)?
