Hi,
Recently I upgraded my servers and migrated Riak from 5 old servers to 5
new ones (new servers are running Riak 2.1.4, old were on 2.1.1).
After running 'riak-admin diag' I got
[warning] The following preflists do not satisfy the n_val:
[[{1450083655789255239155218544960687058564870569984,
'riak@z...'},
{1455792646560079078679451688838485039110401556480,
'riak@a...'},
{0,
'riak@a...'}],
[{1455792646560079078679451688838485039110401556480,
'riak@a...'},
{0,
'riak@a...'},
{5708990770823839524233143877797980545530986496,
'riak@b...'}]]
As I understand it means that no all replicas are located on the same nodes.
I suspect that I can run 'riak-admin cluster leave/join' on some node to
get correct rebalancing. But I remember that few years ago I ran 'riak
attach' and executed some magic Erlang code to make rebalancing. It was on
the same cluster, 4 nodes, Riak 1.x.
Is there a way to do rebalancing without node leave/join in Riak 2.x?
