Hi,
i have one ELS 1.1.2 cluster with 7 nodes.
800GB data.

When i shutdown a node for various reasons, ELS automatically rebalance the 
missing shard on the other node.

To prevent this, I tried this (specified in the official doc) :
"transient" : {
        "cluster.routing.allocation.enable" : "none" }

ans then i issue a node shtudown.

Effectively, the relevant shards are now unassigned and ELS don't try to 
reallocate them.

But when i restart the node, they still remain as "unassigned".
And then when i set back :
"transient" : {
        "cluster.routing.allocation.enable" : "all" }

=>  ELS reallocate unassigned shard to ALL nodes instead of the restarted 
node.

What's wrong ? 
What's the correct procedure ?

regards
jean
