  • If you cluster was installed using MemSQL Ops and was later migrated to using SingleStore Tools, and/or is currently managed by SingleStore Tools: Uninstall using SingleStore Tools

Uninstall using SingleStore Toolbox

Depending on which version of SingleStore Toolbox you use to manage your cluster, you may remove the existing cluster either by a single command, or via sequence of commands.

Removing an existing cluster can be useful for deploying a new SingleStore cluster in its place, or after moving the existing cluster to another set of hosts.

Using either method, the SingleStore Tools-related binaries (Toolbox and client) can safely be deleted once the SingleStore cluster has been removed. If you plan to deploy a new SingleStore cluster, there is no need to delete these binaries.

SingleStore Toolbox 1.6.4 and later

As of SingleStore Toolbox 1.6.4, you may use a single command to remove a SingleStore cluster. The command will delete all data, delete all SingleStore nodes, and unregister all hosts.

Warning

Removing a SingleStore cluster with this command is irreversible.

Run the following command on the Master Aggregator and follow the prompts to remove the cluster.

sdb-deploy destroy-cluster
