PowerScale OneFS 9.8.0.0 Web Administration Guide

Remove a node from the cluster

You can remove a node from an OneFS cluster by smartfailing it. The system smartfails the node to ensure that data on the node is transferred to other nodes in the cluster.

Removing a storage node from a cluster deletes the data from that node and transfers the data to existing nodes. Before the system deletes the data, the FlexProtect job safely redistributes data across the nodes remaining in the cluster.

  1. Navigate to the Cluster Management > Hardware Configuration > Nodes tab.
  2. In the Manage Nodes area, select the node that you want to remove and then click More > Smartfail node. When you remove a storage node, the Cluster Status area displays the smartfail progress. If you remove a non-storage accelerator node, it is immediately removed from the cluster.
    CAUTION: OneFS protects data that is stored on failing nodes or drives through a process called smartfailing. During the smartfail process, OneFS places a device into quarantine. Data stored on quarantined devices is read-only. While a device is quarantined, OneFS reprotects the data on the device by distributing the data to other devices. After all data migration is complete, OneFS logically removes the device from the cluster, the cluster logically changes its width to the new configuration, and the node or drive can be physically replaced. OneFS smartfails devices only as a last resort. Although you can manually smartfail nodes or drives, it is recommended that you first consult Dell Technologies Support. Occasionally a device might fail before OneFS detects a problem. If a drive fails without being smartfailed, OneFS automatically starts rebuilding the data to available free space on the cluster. However, because a node might recover from a failure, if a node fails, OneFS does not start rebuilding data unless the node is logically removed from the cluster.
