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. The failed or left server will
|
|
be garbage collected after 24h.
|
|
|
|
If ACLs are enabled, this option requires a token with the 'agent:write'
|
|
capability.
|
|
|
|
General Options:
|

|
` + generalOptionsUsage(usageOptsDefault|usageOptsNoNamespace) + `
|
|
|
|
Server Force-Leave Options:
|
|
|
|
-prune
|
|
Removes failed or left server from the Serf member list immediately.
|
|
If member is actually still alive, it will eventually rejoin the cluster again.
