Codeigniter: CI SESSION use redis cluster

[brickspert]

sorry,My englisth is so poor。
Now,I want to put the session to redis.
I use the php-redis extension.
when I use the single-instance , I change the config.php to
$config['sess_driver'] = 'redis'; $config['sess_save_path'] = '127.0.0.1:6379';

it works ok.

next,the problem.
I have two server , I want to use the redis cluster . I set the cluster OK.
I use the next code to test it
<?php $redis = new RedisCluster(NULL, Array('127.0.0.1:6380')); $redis->set('test','test'); echo $redis->get('test'); ?>
and I put key value from one server,and I can get the value from other server.so the cluster is OK.

But how change the config.php to connect to redis cluster? I have tried a variety of methods,it not work.The error message is
Warning: Failed to write session data (user). Please verify that the current setting of session.save_path is correct
what can I do? Is CI support redis cluster?
Thank you very much for your help!
