unregister-host

Info

MemSQL Helios does not support this command.

Unregister a host.

Usage

Unregister a host.

Delete a host from the state file. This command will not connect to the host, nor will it perform any operations on its nodes.

To delete all data, delete all nodes, uninstall all `singlestoredb-server` packages, and unregister all SingleStore DB hosts, use `sdb-deploy destroy-cluster` (e.g., to destroy the existing cluster and deploy a new one).

Usage:
  sdb-toolbox-config unregister-host [flags]

Flags:
  -a, --all           Unregister all hosts
  -h, --help          Help for unregister-host
      --host string   The host to unregister

      --backup-cache FILE_PATH                File path for the backup cache
      --cache-file FILE_PATH                  File path for the Toolbox node cache
