Hey guys,

i am struggeling atm with the shard allocation in my ES cluster.

The problem is that i got the index [logstash-2015.04.13] that lays on the  
node "Storage1" with 12 shards. I want that the index get evenly  
distributed to the 2 other "Storage"-nodes, the node with the SSDs in it  
should be avoided for allocation

The settings of the index are:

settings for logstash-2015.04.13

{  
"index" : {  
"routing" : {  
"allocation" : {  
"include" : {  
"tag" : ""  
},  
"require" : {  
"tag" : ""  
},  
"exclude" : {  
"tag" : "SSD"  
},  
"total\_shards\_per\_node" : "4"  
}  
},

Unfortunately i get the following logs in ES:

[2015-04-20 08:01:55,070][DEBUG][cluster.routing.allocation] [SSD] [logstash-2015.04.13][4] allocated on [Node Info of Storage1], but can no longer be allocated on it, moving...  
[DEBUG][cluster.routing.allocation] [SSD] [logstash-2015.04.13][4] can't move

I disabled the disk-based shard allocation to make sure that this isnt the problem.

So is there a way i can see what denies the shard allocation to the other nodes? maybe a log of the Allocation-decider i can enable?

Thanks in advance.
