Enabling and Configuring Disk Balancer

To enable and configure disk space balancer using the Control System:

The disk space balancer checks every storage pool on a regular basis and moves containers from a storage pool when that pool's utilization meets the following conditions:

• The storage pool is over 70% full.
• The storage pool's utilization exceeds the average utilization on the cluster by a specified threshold:
  • When the average cluster storage utilization is below 80%, the threshold is 10%.
  • When the average cluster storage utilization is below 90% but over 80%, the threshold is 3%.
  • When the average cluster storage utilization is below 94% but over 90%, the threshold is 2%.

You can use the config save command to modify disk space balancer parameter values.

Example: # maprcli config save -values {"cldb.balancer.disk.max.switches.in.nodes.percentage":"20"}
