I can see that the demotion is happening from the status provided by you.<br>
Do verify it.<br>
I would recommend you to change the cluster.tier-demote-frequency to 120<br>
and cluster.tier-promote-frequency to 1800 to increase the demotions until the<br>
hot tier is emptied to a certain extent. Later you can use the values<br>
existing now.<br>
