The `leave` command triggers a graceful leave and shutdown of the agent. It is
|
|
|
|
|
used to ensure other nodes see the agent as left instead of failed. Nodes that
|
|
|
|
|
leave will not attempt to re-join the cluster on restarting with a snapshot.

The `leave` command triggers a graceful leave and shutdown of the agent.
|
|
|
|
|
It is used to ensure other nodes see the agent as "left" instead of
|
2014-02-08 00:41:03 +00:00
|
|
|
"failed". Nodes that leave will not attempt to re-join the cluster
|
|
|
|
|
on restarting with a snapshot.

|
|
|
For nodes in server mode, the node is removed from the Raft peer set
|
2014-04-16 04:01:12 +00:00
|
|
|
in a graceful manner. This is critical, as in certain situations a
|
|
|
|
|
non-graceful leave can affect cluster availability.

Depending on how many Consul servers are running, running `consul leave` on a server explicitly can reduce the quorum
|
|
|
|
|
size (which is derived from the number of Consul servers, see
|
|
|
|
|
[deployment_table](/consul/docs/architecture/consensus#deployment_table)).
|
|
|
|
|
Even if the cluster used `bootstrap_expect` to set a number of servers and thus quorum size initially,
|
|
|
|
|
issuing `consul leave` on a server will reconfigure the cluster to have fewer servers.
|
|
|
|
|
This means you could end up with just one server that is still able to commit writes because the quorum size for
|
|
|
|
|
1-server setup is only 1, but those writes might be lost if that server fails before more are added.
