Hi Manu, I see similar vnode distribution in my local dev cluster. This is due to 64 not being evenly divisible by 5.
4 nodes: $ dev1/bin/riak-admin member-status ================================= Membership ================================== Status Ring Pending Node ------------------------------------------------------------------------------- valid 25.0% -- '[email protected]' valid 25.0% -- '[email protected]' valid 25.0% -- '[email protected]' valid 25.0% -- '[email protected]' ------------------------------------------------------------------------------- 5th node added: $ dev1/bin/riak-admin member-status ================================= Membership ================================== Status Ring Pending Node ------------------------------------------------------------------------------- valid 18.8% -- '[email protected]' valid 18.8% -- '[email protected]' valid 18.8% -- '[email protected]' valid 25.0% -- '[email protected]' valid 18.8% -- '[email protected]' ------------------------------------------------------------------------------- Cluster *from scratch* with 5 nodes: $ dev1/bin/riak-admin member-status ================================= Membership ================================== Status Ring Pending Node ------------------------------------------------------------------------------- valid 20.3% -- '[email protected]' valid 20.3% -- '[email protected]' valid 20.3% -- '[email protected]' valid 20.3% -- '[email protected]' valid 18.8% -- '[email protected]' ------------------------------------------------------------------------------- -- Luke Bakken CSE [email protected] On Mon, Jun 2, 2014 at 6:52 AM, Manu Mäki - Compare Group < [email protected]> wrote: > Hi all, > > In the beginning we were running four nodes with n-value of 2.
