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!

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.

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
