Hi, I got a problem of many "unassigned shards". So through some reading I tryed to do : `index.routing.allocation.disable_allocation= false` This returned me: > index.routing.allocation.disable\_allocation please check that any required plugins are installed Looking around I didnt find such plugins. Also I didnt yet see a reference in ES 5.X for "index.routing.allocation.disable\_allocation". Is there such an option in ES 5.2? If no, what should I do? Also if someone knows from what can this problem can happen, and what other solutions are there? ---

Simply setting this won't help unless you have already disabled allocation. So, why are these unallocated? What do your logs show? How many shards, are they primary or replica? ---

I though I found a magic answer 🙂 I dont know why, the machines that I am working on are not from our company but an outside one. From my understanding they copied the VM of the ES a few times, and copied the VMs of from where the filebeats sends the logs to ES What logs? I actualy don't understand enough in shards. So I can't answer the 3rd question. When looking at the logs of logstash, I get: error: "failed to derive xcontent" (but I am not sure this is connected) (Thanks on the quick reply) ---

What does `_cat/allocation` show? ---

Since the machine I am working on is secure I cant copy paste from there or work with internet therefore I will not copy but type in the releavent parts: I got a bunch of numbers then KppASWN and then I got: 51 UNASSIGNED ---

How many nodes in your cluster? ---

When I did: \_nodes/process it shows me only one node: > "\_nodes": { > "total" : 1, > ... ), > cluster\_name : elasticsearch, > nodes : { > "details of only one node" > } ---

by the way: when I typed in \_cat /allocation: one of the numbers that was in kppASWN... was 51 and also it was in the UNASSIGNED section ---

Then everything is ok. You cannot assign replica and primary shards to a single node, so to clear that up you need another node, or to remove the replicas. ---

So if I open a new ElasticSearch instance (which opens a new node) this will fix the problem? A few questions regarding this: 1- how to erase replicas? 2 - how did this happen how did replicas come upon? 3 - how opening a new node will solve it, does ES know how to allocate shards automatically? ---

I probably will erase the replicas for a fast answer and build later a new node (another ES) ---

Replica's are added by default and will be automatically assigned by ES if you add more nodes to the cluster. You can dynamically change the number of replicas using something like; `curl -XPUT localhost:9200/*/_settings -d '{ "index" : { "number_of_replicas" : 0 } }'`. ---
