You can decommission and permanently remove one or more Storage Nodes, Gateway Nodes, or non-primary Admin Nodes from the StorageGRID system.

About this task

You cannot decommission a grid node if doing so will leave the StorageGRID in an invalid state. The following rules are enforced:

Note: When you decommission a Storage Node, the following alarms might be raised:
  • VSTU (Object Verification Status). This notice-level alarm indicates that the Storage Node is going into maintenance mode during the decommission process.
  • CASA (Data Store Status). This major-level alarm indicates that the Cassandra database is going down because services have stopped.
