Thank you very much for you reply gregor.
About movePrimary, I've read the documentation and it seem to need a empty
shard to do the movePrimary
*
Important
Only use movePrimary<http://docs.mongodb.org/manual/reference/commands/#movePrimary>
when:
*
- *the database does not contain any collections with data, or*
- *you have drained all sharded collections using the
removeShard<http://docs.mongodb.org/manual/reference/commands/#removeShard>
command.*
*See Remove Shards from an Existing Sharded
Cluster<http://docs.mongodb.org/manual/tutorial/remove-shards-from-cluster/>
for
a complete procedure.*
because all my shards has data and this is a production cluster.
I'm rigtht?
