Command: server force-leave
server force-leave command forces a server to enter the "left" state.
This can be used to eject server nodes which have failed and will not rejoin
the cluster. The failed or left server will be garbage collected after
Note that if the server is actually still alive, it will eventually rejoin the cluster again.
nomad server force-leave [options] <node>
This command expects only one argument - the node which should be forced to enter the "left" state.
Additionally, by specifying the
prune flag, a failed or left node can be forcibly removed

-token: The SecretID of an ACL token to use to authenticate API requests with. Overrides the
