Unable to add a third node in riak - This node is already a member of a cluster

I have 2 nodes inside a riak ring. I tend to add third node

172.30.1.252

ubuntu@ip-172-30-1-252:~/riak$ sudo riak-admin status | grep ring_members
ring_members : ['[email protected]','[email protected]']
ubuntu@ip-172-30-1-252:~/riak$ sudo riak-admin cluster join [email protected]
Failed: This node is already a member of a cluster
ubuntu@ip-172-30-1-252:~/riak$

But, in my 172.30.1.249, it doesn't join any other cluster.

172.30.1.249

ubuntu@ip-172-30-1-249:~/riak$ sudo riak-admin cluster leave
Failed: '[email protected]' is the only member.

I event try to start and stop again.

ubuntu@ip-172-30-1-249:~/riak$ sudo riak stop
ok
ubuntu@ip-172-30-1-249:~/riak$ sudo riak start
!!!!
!!!! WARNING: ulimit -n is 1024; 65536 is the recommended minimum.
!!!!
ubuntu@ip-172-30-1-249:~/riak$

But, I'm keep getting Failed: This node is already a member of a cluster when I try to execute join command from 172.30.1.252

Any idea?

Solution

  • Execute join from 172.30.1.249.

    sudo riak-admin cluster join [email protected]

    Riak is right, 172.30.1.252 is already a member of ['[email protected]','[email protected]'].
