Hello Kevin,


Not as i know of, i'm practicing the setup and had no databases on the
system (i have two independant couch-N nodes). I installed and
configured as well as i could using the wiki and common sense and some
luck. Then i simply created a new database (using the old google wiki as
a reference) but nothing happened, not even the problem described by
futon not being able to handle database creation correctly.

What did happen is what you see in the log, of course i could only see
it after doing several operations at first because of the imposed limit
in the python replicator. It smells like an error in my shards.conf but
it shouldn't be! It's the simple [0,1],[1,0] + [couch-1, couch-2] thing!


Thanks so far
