Performing the decommission

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:

Steps

  1. Navigating to the Decommission page
    When you access the Decommission page in the Grid Manager, you can see at a glance which nodes can be decommissioned.
  2. Decommissioning disconnected grid nodes
    You might need to decommission a grid node that is not currently connected to the grid (one whose Health is Unknown or Administratively Down).
  3. Decommissioning connected grid nodes
    You can decommission and permanently remove grid nodes that are connected to the grid.
  4. Pausing and resuming the decommission process for Storage Nodes
    If necessary, you can pause the decommission procedure for a Storage Node during certain stages. You must pause decommissioning on a Storage Node before you can start a second maintenance procedure. After the other procedure is finished, you can resume decommissioning.
  5. Troubleshooting decommissioning
    If the decommissioning process stops because of an error, you can take specific steps to troubleshoot the problem.
