Hi guys, I would really appreciate some help understanding what's going down with shard allocation in this case:
Elasticsearch version: 1.4.4 We had 3 nodes with 1 shard and 1 replica per index (so net 2 copies of everything). 1 node went down and the cluster went red. It started to reallocate shards as expected and there were originally ~50 unallocated shards with 15 primary and the rest replicas. It's been a few hours now and there are still 15 outstanding shards that are all primary that don't seem to be getting re-allocated. I thought this would be a pretty standard scenario so I was really hoping I wouldn't need to manually walk through and re-allocate the primary shards, but I'm not sure what else to try at this point to get back to green. Any pointers would be really appreciated. Here is some of the relevant seeming bits folks asked about on the IRC: In the ES logs for the unallocated index names there are lines along the line of [2015-04-29 22:08:22,803][DEBUG][action.admin.indices.stats] [Agent Axis] [webaccesslogs-2015.04.24][0], node[-r2iQnH4R-mcUy4NicCB5g], [P], s[STARTED]: failed to execute [org.elasticsearch.action.admin.indices.stats.IndicesStatsRequest@6a564a91] org.elasticsearch.transport.SendRequestTransportException: [Jean-Paul Beaubier][inet[/10.155.165.126:9300]][indices:monitor/stats[s]] "Jean-Paul Beaubier" is the node that went down _cat/recovery shards disk.used disk.avail disk.total disk.percent host ip node 420 21.2gb 77gb 98.3gb 21 ip-10-234-164-148 10.234.164.148 Agent Axis 420 41gb 57.2gb 98.3gb 41 ip-10-218-145-237 10.218.145.237 Ebon Seeker 15 UNASSIGNED I'm trying to understand why it's stuck in this state given there is no other info in the logs as far as I can tell about why the shards can't be allocated. Shouldn't the replicas just be promoted in place to new primaries and then new replicas created on the other node?
