Usage: nomad server force-leave [options] <node>
|
|
|
|
Forces an server to enter the "left" state. This can be used to
|
|
eject nodes which have failed and will not rejoin the cluster.
|
|
Note that if the member is actually still alive, it will
|
|
eventually rejoin the cluster again.
|
|
|
|
If ACLs are enabled, this option requires a token with the 'agent:write'
|
|
capability.
