Decommissioning connected grid nodes

You can decommission and permanently remove nodes that are connected to the grid.

Before you begin

Attention: Do not remove a grid node's virtual machine or other resources until instructed to do so in this procedure.

Procedure

  1. From the Decommission Nodes page, select the check box for each grid node you want to decommission.
  2. Enter the provisioning passphrase.
    The Start Decommission button is enabled.
  3. Click Start Decommission.
    A confirmation dialog box appears.

  4. Review the list of selected nodes, and click OK.
    The node decommission procedure starts, and the progress is displayed for each node. During the procedure, a new Recovery Package is generated to show the grid configuration change.

    Attention: Do not take a Storage Node offline after the decommission procedure has started. Changing the state might result in some content not being copied to other locations.
  5. As soon as the new Recovery Package is available, click the link or select Maintenance > System > Recovery Package to access the Recovery Package page. Then, download the .zip file.
    See the instructions for downloading the Recovery Package.
    Note: Download the Recovery Package as soon as possible to ensure you can recover your grid if something goes wrong during the decommission procedure.
  6. Periodically monitor the Decommission Nodes page to ensure that all selected nodes are decommissioned successfully.
    Storage Nodes can take days or weeks to decommission. When all tasks are complete, the node selection list is redisplayed with a success message.

  7. Follow the appropriate step for your platform. For example:
    • Linux: You might want to detach the volumes and delete the node configuration files you created during installation.
    • VMware: You might want to use the vCenter Delete from Disk option to delete the virtual machine. You might also need to delete any data disks that are independent of the virtual machine.
    • StorageGRID appliance: The appliance node automatically reverts to an undeployed state where you can access the StorageGRID Appliance Installer. You can power off the appliance or add it to another StorageGRID system.
