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 `memsql-server` packages, and unregister all MemSQL hosts, use `memsql-deploy destroy-cluster` (e.g., to destroy the existing cluster and deploy a new one).

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

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

Global Flags:
      --backup-cache FILE_PATH              File path for the backup cache
      --cache-file FILE_PATH                File path for the Toolbox node cache
  -c, --config FILE_PATH                    Toolbox configuration file path
      --disable-spinner                     Disable the progress spinner, which some terminal sessions/environments may have issues with
  -j, --json                                Enable JSON output
      --parallelism POSITIVE_INTEGER        Maximum number of operations to run in parallel
      --runtime-dir DIRECTORY_PATH          Where to store Toolbox runtime data
      --ssh-max-sessions POSITIVE_INTEGER   Maximum number of SSH sessions to open per host, must be at least 3
      --state-file FILE_PATH                Toolbox state file path
  -v, --verbosity count                     Increase logging verbosity: valid values are 1, 2, 3. Usage -v=count or --verbosity=count
  -y, --yes                                 Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default

Remarks

This command is interactive unless you use either the --yes or --json flags to override interactive behavior.
