»Consul Operator Raft
consul operator raft
The Raft operator command is used to interact with Consul's Raft subsystem. The command can be used to verify Raft peers or in rare cases to recover quorum by removing invalid peers.
Usage: consul operator raft <subcommand> [options] The Raft operator command is used to interact with Consul's Raft subsystem. The command can be used to verify Raft peers or in rare cases to recover quorum by removing invalid peers. Subcommands: list-peers Display the current Raft peer configuration remove-peer Remove a Consul server from the Raft configuration
This command displays the current Raft peer configuration.
consul operator raft list-peers -stale=[true|false]
-stale- Optional and defaults to "false" which means the leader provides the result. If the cluster is in an outage state without a leader, you may need to set this to "true" to get the configuration from a non-leader server.
The output looks like this:
Node ID Address State Voter RaftProtocol alice 127.0.0.1:8300 127.0.0.1:8300 follower true 2 bob 127.0.0.2:8300 127.0.0.2:8300 leader true 3 carol 127.0.0.3:8300 127.0.0.3:8300 follower true 2
Node is the node name of the server, as known to Consul, or "(unknown)" if
the node is stale and not known.
ID is the ID of the server. This is the same as the
Address in Consul 0.7
but may be upgraded to a GUID in a future version of Consul.
Address is the IP:port for the server.
State is either "follower" or "leader" depending on the server's role in the
Voter is "true" or "false", indicating if the server has a vote in the Raft
configuration. Future versions of Consul may add support for non-voting servers.
This command removes the Consul server with given address from the Raft configuration.
There are rare cases where a peer may be left behind in the Raft configuration
even though the server is no longer present and known to the cluster. This command
can be used to remove the failed server so that it is no longer affects the
Raft quorum. If the server still shows in the output of the
consul members command, it is preferable to
clean up by simply running
instead of this command.
consul operator raft remove-peer -address="IP:port"
-address- "IP:port" for the server to remove. The port number is usually 8300, unless configured otherwise.
-id- ID of the server to remove.
The return code will indicate success or failure.
