You can decommission and permanently remove one or more Storage Nodes, API Gateway Nodes, or non-primary Admin Nodes from the StorageGRID Webscale system.
About this task
You cannot decommission a grid node if doing so will leave the StorageGRID Webscale in an invalid state. The following rules are enforced:
- You cannot decommission the primary Admin Node.
- You cannot decommission Archive Nodes.
- You cannot decommission a Storage Node if its removal would affect the ADC quorum.
- You cannot decommission a Storage Node if it is required for the active ILM policy.
- You cannot decommission a connected grid node if your grid includes any disconnected grid nodes (nodes whose health is Unknown or Administratively Down). If your grid includes any disconnected nodes, you must bring them back online, recover them, or decommission them while they are disconnected.
