Reviewing warnings and preconditions for node recovery

Always recover a failed grid node as soon as possible. Review all warnings and preconditions for node recovery before beginning.

About this task

You must always recover a failed grid node as soon as possible. A failed grid node may reduce the redundancy of data in the StorageGRID Webscale system, leaving you vulnerable to the risk of permanent data loss in the event of another failure. Operating with failed grid nodes can have an impact on the efficiency of day‐to‐day operations, can increase recovery time (when queues develop that need to be cleared before recovery is complete), and can reduce your ability to monitor system operations.

All of the following conditions are assumed when recovering grid nodes:
  • The failed physical or virtual hardware has been replaced and configured.
  • If you are recovering a grid node other than the primary Admin Node, there is connectivity between the grid node being recovered and the primary Admin Node.

Always follow the recovery procedure for the specific type of grid node you are recovering. Recovery procedures vary for primary or non-primary Admin Nodes, API Gateway Nodes, Archive Nodes, appliance Storage Nodes, and virtual Storage Nodes.
