Usage

Usage:
  memsqlctl delete-node [flags]

Flags:
  -a, --all                 Delete all nodes on the machine
  -h, --help                help for delete-node
      --memsql-id strings   MemSQL ID to delete

Global Flags:
  -c, --config FILE_PATH                     Path to the memsqctl config file
      --default-install-dir DIRECTORY_PATH   Path to the default install directory
  -j, --json                                 Print output in JSON format
      --node-metadata-file FILE_PATH         Path to the node metadata file
      --parallelism int                      Maximum amount of operations to be run in parallel
      --ssl-ca FILE_PATH                     Path to the CA certificate file in PEM format to authenticate the MemSQL server certificate
      --timeout duration                     Maximum time for operation to complete (e.g., 30s, 10m, 1.5h)
  -v, --verbosity count                      Increase logging verbosity
  -y, --yes                                  Enable non-interactive mode and assume the user would like to move forward with the proposed actions by default

Remarks

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

If --memsql-id, or --memsql-cnf, or --all is not specified, memsqlctl will prompt the user to select a node from a table list of nodes.

If --memsql-cnf is specified, memsqlctl will attempt to first delete the specified directories in the config (datadir, plancachedir, tracelogsdir, etc.). Finally, memsqlctl will delete the memsql.cnf file itself and its record in the node metadata file, nodes.hcl.

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

Output

The following is the standard output for the delete-node command.

$ sudo memsqlctl delete-node
memsqlctl will perform the following actions:
  · Delete MemSQL node
    - Base directory and contents: /var/lib/memsql/61cbf018-4256-4c43-82a7-530220e5817b
