The first node cpu usage is always high during rebalance compare with rest of the cluster nodes.To reduce the cpu usage of rebalancer datanode( node1), i peer a new node( without disk) for rebalance and start the rebalancer. It starts again the rebalancer on same node1.

Cluster.min-free-disk controls new file creation on the bricks. If you happen to write to the existing files on the brick and that is leading to brick getting full, then most probably you should run a rebalance.<br>

Hi,<br>
<br>
<br>
I have a cluster of 720 bricks, all bricks are 4TB in size. I have change the cluster.min-free-disk default value 10% to 3%. So all the disks should have 3% minimum disk space free. But some cluster disks are getting full now. Is there any additional configuration for keeping some percentage of disk space kept free?<br>
<br>
