Is there a way to determine the number of questions per shard? I have a 6 node cluster which was evenly balanced traffic/load wise. When I added a 7th node and rebalancing took place the 7th server's cpu usage went to 100%. My quick solution was to randomly move 2 non-primary shards off to other nodes. Of course it was eventually rebalanced so 2 shards were moved back to the 7th node. This has fixed the problem for now. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

Hey, can you elaborate, what exactly you mean with "questions per shard"? When you add another node to your cluster, usually a rebalancing of data happens from some of the other nodes to the new nodem which is a resource intensive operation. But it seems, you know, so I'd like to know more about your case and what exactly has happened in order to find out if this is a bug or a feature? --Alex On Wed, Sep 25, 2013 at 12:20 AM, [daveo@weheartit.com](mailto:daveo@weheartit.com) wrote: > Is there a way to determine the number of questions per shard? > > I have a 6 node cluster which was evenly balanced traffic/load wise. > When I added a 7th node and rebalancing took place the 7th server's cpu > usage went to 100%. > My quick solution was to randomly move 2 non-primary shards off to other > nodes. > Of course it was eventually rebalanced so 2 shards were moved back to the > 7th node. > This has fixed the problem for now. > > -- > You received this message because you are subscribed to the Google Groups > "elasticsearch" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [elasticsearch+unsubscribe@googlegroups.com](mailto:elasticsearch+unsubscribe@googlegroups.com). > For more options, visit [https://groups.google.com/groups/opt\_out](https://groups.google.com/groups/opt_out). -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
