Completely removes a node and its data from a host.

This command removes the specified node from the cluster and deletes its data. If the node is a leaf node, this command will also rebalance the leaf node’s partitions into the remaining cluster.

To remove a leaf node from the cluster without deleting its data, and with the ability to add it back to the cluster, refer to the sdb-admin remove-leaf command.

A node must be stopped before it can be deleted. Use the stop-node command to perform this action.

Before deleting a leaf node, sdb-admin delete-node runs the remove-leaf command to remove it from the cluster. Removing the leaf node transfers its data to other leaves in the cluster and prevents data loss (in case HA is not enabled).

As of Toolbox 1.2.2, sdb-admin delete-node removes all the data on the node and deletes the node’s record from the node metadata file, nodes.hcl.

Note that this action is only reversible by deploying a new leaf in the same location, attaching it, and rebalancing partitions.

This command will perform the following actions on the specified node(s):

  • REMOVE <LEAF|AGGREGATOR> from the Master Aggregator

  • Delete all the node-related directories (data, auditlogs, plancache, tracelogs, etc.)

It will not:

To destroy the existing cluster by deleting all data, deleting all nodes, uninstalling all singlestoredb-server packages, and unregistering all hosts so a new cluster can be deployed, use sdb-deploy destroy-cluster.
