SingleStore Managed Service does not support this command.
Delete a SingleStore DB node on a specific host.
Delete a SingleStore DB node on a specific host. This command will perform the following actions on the SingleStore DB node(s): - `REMOVE LEAF/AGGREGATOR` from the Master Aggregator - delete all the node-related directories (data, auditlogs, plancache, tracelogs, etc.) It will NOT: - uninstall `singlestoredb-server` from the host (use `sdb-deploy uninstall` to do so) - unregister the host from Toolbox (use `sdb-toolbox-config unregister-host` to do so) 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-admin delete-node [flags] Flags: -a, --all Delete all nodes in the cluster -h, --help Help for delete-node --memsql-id MemsqlID The node ID of the node to delete --skip-remove Skip removing the leaves and aggregators --stop Stop each node before deletion 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 File path for the Toolbox configuration --disable-colors Disable color output in console, which some terminal sessions/environments may have difficulty with --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-control-persist SECONDS Enable SSH ControlPersist and set it to the specified duration in seconds --ssh-max-sessions POSITIVE_INTEGER Maximum number of SSH sessions to open per host, must be at least 3 --ssh-strict-host-key-checking Enable strict host key checking for SSH connections --ssh-user-known-hosts-file FILE_PATH Path to the user known_hosts file for SSH connections. If not set, /dev/null will be used --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
- A node must be stopped before it can be deleted. Use the stop-node command to perform this action.
- Starting from
sdb-admin delete-noderemoves all the data on the node and deletes the node’s record from the node metadata file,
- Before deleting a leaf node,
sdb-admin delete-noderuns 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).
- This command is interactive unless you use either the
--jsonflags to override interactive behavior.
