Hi, i am using elasticsearch for a while and one morning i have noticed i have an unassigned shard. i started to play with the cluster (restart some nodes, add more nodes, try to move allocate the shards) and got some more unassigned i realized all the shards which are primary in one of the nodes has their replicas unassigned. also, i tired to allocate or move those shards, and all i get is: org.elasticsearch.transport.RemoteTransportException: [foa02][inet[/192.168.2.2:9300]][cluster/reroute] Caused by: org.elasticsearch.ElasticSearchIllegalArgumentException: [allocate] allocation of [logstash-2014.02.18][0] on node [foa8][Rhmt4uF6Rf2\_8WAw-WieZA][inet[192.168.2.8/192.168.2.8:9300]]{master=false} is not allowed, reason: NO() at org.elasticsearch.cluster.routing.allocation.command.AllocateAllocationCommand.execute(AllocateAllocationCommand.java:188) at org.elasticsearch.cluster.routing.allocation.command.AllocationCommands.execute(AllocationCommands.java:116) at org.elasticsearch.cluster.routing.allocation.AllocationService.reroute(AllocationService.java:125) at org.elasticsearch.action.admin.cluster.reroute.TransportClusterRerouteAction$1.execute(TransportClusterRerouteAction.java:112) at org.elasticsearch.cluster.service.InternalClusterService$UpdateTask.run(InternalClusterService.java:300) at org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.run(PrioritizedEsThreadPoolExecutor.java:135) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:724) i attached an image from the "head" plugin [https://lh4.googleusercontent.com/-lQxXqu8G1jc/UwSh5GyXkuI/AAAAAAAAGV0/ZfnsveGeA30/s1600/head.jpg](https://lh4.googleusercontent.com/-lQxXqu8G1jc/UwSh5GyXkuI/AAAAAAAAGV0/ZfnsveGeA30/s1600/head.jpg) any idea what is wrong? -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.

There's a lot of info missing: how many servers, indexes, shards and replicas do you have? have you made sure to set all the configurations correctly (quorum size, expected number of nodes etc)? You may be experiencing a split-brain situation (if your cluster state is red) or just a temporary hiccup (if it's yellow). But without more info its hard to tell. Either way, restarting the entire cluster usually helps immediately, if this is an option. With regards to the response "is not allowed, reason: NO()" you are getting, there is an open issue on this for getting more feedback in the response, that I _think_ was made it to v1 and maybe even 0.90.11. -- Itamar Syn-Hershko [http://code972.com](http://code972.com) | @synhershko [https://twitter.com/synhershko](https://twitter.com/synhershko) Freelance Developer & Consultant Author of RavenDB in Action [http://manning.com/synhershko/](http://manning.com/synhershko/) On Wed, Feb 19, 2014 at 2:22 PM, Tal Shemesh [tal.shemesh@gmail.com](mailto:tal.shemesh@gmail.com) wrote: > Hi, > i am using elasticsearch for a while and one morning i have noticed i have > an unassigned shard. > i started to play with the cluster (restart some nodes, add more nodes, > try to move allocate the shards) and got some more unassigned > i realized all the shards which are primary in one of the nodes has their > replicas unassigned. > also, i tired to allocate or move those shards, and all i get is: > > org.elasticsearch.transport.RemoteTransportException: > [foa02][inet[/192.168.2.2:9300]][cluster/reroute] > Caused by: org.elasticsearch.ElasticSearchIllegalArgumentException: > [allocate] allocation of [logstash-2014.02.18][0] on node > [foa8][Rhmt4uF6Rf2\_8WAw-WieZA][inet[ > 192.168.2.8/192.168.2.8:9300]]{master=false}[http://192.168.2.8/192.168.2.8:9300]]{master=false}](http://192.168.2.8/192.168.2.8:9300%5D%5D%7Bmaster=false%7D)is not allowed, reason: NO() > at > org.elasticsearch.cluster.routing.allocation.command.AllocateAllocationCommand.execute(AllocateAllocationCommand.java:188) > at > org.elasticsearch.cluster.routing.allocation.command.AllocationCommands.execute(AllocationCommands.java:116) > at > org.elasticsearch.cluster.routing.allocation.AllocationService.reroute(AllocationService.java:125) > at > org.elasticsearch.action.admin.cluster.reroute.TransportClusterRerouteAction$1.execute(TransportClusterRerouteAction.java:112) > at > org.elasticsearch.cluster.service.InternalClusterService$UpdateTask.run(InternalClusterService.java:300) > at > org.elasticsearch.common.util.concurrent.PrioritizedEsThreadPoolExecutor$TieBreakingPrioritizedRunnable.run(PrioritizedEsThreadPoolExecutor.java:135) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) > at java.lang.Thread.run(Thread.java:724) > i attached an image from the "head" plugin > > [https://lh4.googleusercontent.com/-lQxXqu8G1jc/UwSh5GyXkuI/AAAAAAAAGV0/ZfnsveGeA30/s1600/head.jpg](https://lh4.googleusercontent.com/-lQxXqu8G1jc/UwSh5GyXkuI/AAAAAAAAGV0/ZfnsveGeA30/s1600/head.jpg) > > any idea what is wrong? > > -- > 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). > To view this discussion on the web visit > [https://groups.google.com/d/msgid/elasticsearch/c2a5ba79-3bfd-41c5-981f-6e535c6c0052%40googlegroups.com](https://groups.google.com/d/msgid/elasticsearch/c2a5ba79-3bfd-41c5-981f-6e535c6c0052%40googlegroups.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.
