rpk cluster partitions balancer-status
Queries cluster for partition balancer status:
If continuous partition balancing is enabled, redpanda will continuously reassign partitions from both unavailable nodes and from nodes using more disk space than the configured limit.
This command can be used to monitor the partition balancer status.

Balancer status
Balancer status | Description |
---|---|
|
The balancer is disabled. |
|
The balancer is active but there is nothing to do |
|
The balancer is starting but has not run yet. |
|
The balancer is active and is in the process of scheduling partition movements. |
|
Violations have been detected and the balancer cannot correct them. |
Stalled Balancer
A stalled balancer can occur for a few reasons and requires a bit of manual investigation. A few areas to investigate:
-
Are there are enough healthy nodes to which to move partitions? For example, in a three node cluster, no movements are possible for partitions with three replicas. You will see a stall every time there is a violation.
-
Does the cluster have sufficient space? If all nodes in the cluster are utilizing more than 80% of their disk space, rebalancing cannot proceed.
-
Do all partitions have quorum? If the majority of a partition’s replicas are down, the partition cannot be moved.
-
Are any nodes in maintenance mode? Partitions are not moved if any node is in maintenance mode.
