You must review the considerations for removing grid nodes and confirm no repair jobs are active for erasure-coded data.
Considerations for removing grid nodes
Before you start this procedure to remove one or more nodes, you must understand the implications of removing each type of node. Upon the successful decommissioning of a node, its services will be disabled and the node will be automatically shut down.
Checking data repair jobs
Before removing a grid node, you must confirm that no data repair jobs are active. If any repairs have failed, you must restart them before performing the decommission procedure. If you need to decommission a disconnected Storage Node, you will also complete these steps after the decommission procedure completes. You must ensure that any erasure-coded fragments that were on the removed node have been restored successfully.
