You can decommission and permanently remove one or more Storage Nodes, API Gateway Nodes, or non-primary Admin Nodes from the StorageGRID Webscale system. You cannot decommission primary Admin Nodes or Archive Nodes.
The StorageGRID Webscale system prevents you from decommissioning a grid node if it will leave the StorageGRID Webscale in an invalid state. The following is enforced:
If a Storage Node fails while you are decommissioning another Storage Node, wait for the decommissioning process to complete before recovering the failed Storage Node.
Decommissioning procedures may take days or weeks to complete. If needed, you can pause the decommissioning procedure during specific stages.
This notifies the rest of the StorageGRID Webscale system that the grid node has been decommissioned and is no longer available for system operations.
Migrates object data off the decommissioned Storage Node, truncating file lengths to zero to mark progress.
If a Storage Node is offline while decommissioning is in progress, the Storage Node detects the pending decommissioning task when it rejoins the StorageGRID Webscale system and proceeds with data migration as described above.
If you have not done so already, be sure to download the new Recovery Package.
After the decommissioning procedure, ensure that the drives of the decommissioned grid node are wiped clean. Use a commercially available data wiping tool or service to permanently and securely remove data from the drives.
