</div></div>Hi,<br>
<br>
use of utilization (balanced strategy) has one caveat: resources are not moved just because of utilization of one node is less, when nodes have the same allocation score for the resource.<br>
So, after the simultaneus outage of two nodes in a 5-node cluster, it may appear that one node runs two resources and two recovered nodes run nothing.<br>
<br>
Original 'utilization' strategy only limits resource placement, it is not considered when choosing a node for a resource.<br>
