Hi. I saw before this warning with clusters with not enough nodes.
On this case, the environment is amazon ec2 c1.xlarge machines in the same
availability zone. 5 machines. Manage with chef and the oficial riak
cookbook 2.2.0 that installs riak 1.4.0 build 1.
The process:
knife ssh "roles:riak" "riak-admin cluster join riak@node01"
ssh node01 riak-admin cluster plan
ssh node01 riak-admin cluster commit
In the plan face, it already says:
WARNING: Not all replicas will be on distinct nodes
And after commit, riak-admin diag confirms that:
[warning] The following preflists do not satisfy the n_val: [[{0,
'riak@node02
'},
{2854495385411919762116571938898990272765493248,
'riak@node02
'},
{5708990770823839524233143877797980545530986496,
[....] (with
metions to all the nodes)
The solution I found was:
In node01 (or probably any). riak-admin cluster leave. Wait
till transfers finish, and join again.
After this tedious process (30 minuts every cluster commit), riak-diag no
longer mentions nothing.
I do this process to times, with the same result, and needing to apply the
same solution.
Any way to skip this? I am doing something wrong?
Thanks.
