How can I remove a node from my galera cluster?

Question

Is there any better way of doing it,apart from setting 'wsrep_cluster_address='gcomm://' for each node that I want to remove?

Might this help? http://galeracluster.com/documentation-webpages/autoeviction.html — Rick James, Sep 08 '15 at 21:18
But all the methods are based on some values,satisfying which the node gets removed.But what I am looking for is to remove the node manually,at any given point of time? — , Sep 09 '15 at 11:00

I just did this. Seems to have worked. On the node you want to evict

Try

>show global status like 'wsrep%';

Copy paste the wsrep_gcomm_uuid

Go to another node and evict from there assuming the UUID = 1de97dad-f609-11e5-8a50-ce2e621b0c42

SET GLOBAL wsrep_provider_options="evs.evict=1de97dad-f609-11e5-8a50-ce2e621b0c42";

If the node is already shut down or non-responsive you can get the UUID from any other node from wsrep_evs_delayed

I see two choices here:

(You aren't doing RSU, but that involves "removing a node".)
