Managing Volume Balancer

Explains the CLI commands that you can use to balance the containers of a volume.

Enabling and Disabling the Volume Balancer

The volume balancer is disabled by default. To enable or disable the volume balancer:

Set the value for the cldb.volume.balancing.enable parameter using the config save command. To:

After enabling the volume balancer feature, you must run the volume balancecontainers command to balance the containers associated with a volume.
