Hi, I have a cluster from 5 nodes, where I store the information from the logstash. Recently I've tried to increase the number of shards in the logstash index to 20 (from 5).
>From the beginning everything went well, all the shards were allocated and the cluster state was green. But, currently, when the new index is started (at the beginning of the day), I met the situation when some shards are not allocated: <https://lh3.googleusercontent.com/-R3bWkXbXCbU/VGmwngnPOzI/AAAAAAAAAKY/9n8XlVCGPyc/s1600/Screen%2BShot%2B2014-11-17%2Bat%2B10.23.04%2BAM.png> Nothing happens during the day, while I thing the cluster has resources. If I would restart some nodes from the cluster, it could turn out that all the shards would be allocated. The idea which I'm trying to reach - more shards => each shard is smaller => it would allocate them faster, it would index faster, because of the indexing on each shard. Questions: 1. Why it is not able to allocate those shards during the index creation? 2. Why it does not allocate those shards during the day? 3. What is the recommended shards number for N nodes? Any thoughts are welcome. Regards, -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
