5.1.8. Percent DataNodes with space available

This service-level alert is triggered if the storage if full on a certain percentage of DataNodes (10% warn, 30% critical). It uses the check_aggregate.php plug-in which aggregates the result from the check_datanode_storage.php plug-in. Potential causes
  • Cluster storage is full

  • If cluster storage is not full, DataNode is full Possible remedies
  • If cluster still has storage, use Balancer to distribute the data to relatively less used DataNodes

  • If the cluster is full, delete unnecessary data or add additional storage by adding either more DataNodes or more or larger disks to the DataNodes. After adding more storage run Balancer
