If the node decommission procedure stops because of an error, you can take specific steps to troubleshoot the problem.
You must be signed in to the Grid Manager using a supported web browser.
If you shut down the grid node being decommissioned, the task stops until the grid node is restarted. The grid node must be online.
Select SUPPORT > Tools > Grid topology.
In the Grid Topology tree, expand each Storage Node entry, and verify that the DDS and LDR services are both online.
To perform Storage Node decommissioning, all nodes and all services need to be healthy at the start of an online node/site decommissioning.
To view the active grid tasks, select primary Admin Node > CMN > Grid Tasks > Overview.
Check the status of the decommissioning grid task.
If the status of the decommissioning grid task indicates a problem with saving grid task bundles, select primary Admin Node > CMN > Events > Overview
Check the number of Available Audit Relays.
If the attribute Available Audit Relay is one or greater, the CMN service is connected to at least one ADC service. ADC services act as Audit Relays.
The CMN service must be connected to at least one ADC service and a majority (50 percent plus one) of the StorageGRID system’s ADC services must be available in order for a grid task to move from one stage of decommissioning to another and finish.
If the CMN service is not connected to enough ADC services, ensure that Storage Nodes are online, and check network connectivity between the primary Admin Node and Storage Nodes.
