Hi

In my setup everything worked fine until I upgraded to riak 1.2
(although this may be a coincidence)
Nodes are installed from scratch with changes only to db backend (I'm
using eLevelDB)
and names.
For some reason node cannot join to another.
What am I doing wrong?

I'm using Ubuntu 10.04 but I've seen the same behaviour on Ubuntu 12.04
I may miss openssl dependency. I don't know if that matters

Daniel,

Cluster operations (invoked by `riak-admin cluster`) are now multi-phase.
 Instead of calling an operation and it taking effect immediately you need
to stage your changes, view your changes, and then commit them.  E.g.

riak-admin cluster join blah

riak-admin cluster plan

riak-admin cluster commit

There is an `-f` option to keep the old behavior but we recommend against
this.  Staged clustering was put in place to keep users from hurting their
clusters and to make multiple changes more efficient.

-Z

Speaking of joining clusters . . .

I'm in the middle of writing a CFEngine promise to automatically install
Riak, configure it and join a cluster.

Is it best to have all nodes issue a 'riak-admin cluster join' command
before a single node issues the final 'riak-admin cluster commit'
command? (Potentially hard to do with CFEngine) Or is it OK to have each
node issue its own 'join' and 'commit' commands? (Reasonably easy)

Or is it a bad idea to build the cluster automatically and I should
really be doing it manually?

Secondly, is there a riak-admin command or status value that
definitively says "This node is part of a cluster" (even if all other
nodes in the cluster are down) so that CFEngine knows not to re-issue
the cluster join command a second time?

Thanks!

It might be worth looking at the Chef cookbook for how it does it. As
I see it on a fresh install with no data, there's probably not much
major risk in concurrent joins. On an existing install, however, I'd
think you would want to go serially.

We stand up all of our riak clusters from scratch using the chef
cookbook from Basho and it works fine but we do it serially with 3
nodes as the base. Haven't gotten to the point where we need to bump
up to 5 nodes (and thus not had to tackle the addition of those
nodes).

Thanks Ryan!

I'll give it a try. Where I can find details about it, parameters options etc.?

Just type riak-admin cluster and it will print the help message.
