Hi,  
I am using ElasticSearch version 1.5.0.

Our ElasticSearch cluster has 8 shards with 1 replica, hosted on 7 data  
nodes + 1 master node with setting below:

gateway.recover\_after\_nodes: 4  
gateway.recover\_after\_time: 5m  
gateway.expected\_nodes: 6

After a few nodes were restarted at the same time, 2 out of 7 shards (both  
Primary and Replicat) are in UNASSIGNED status.  
Here are my findings when I check the shards data folder for these 2  
UNASSIGNED shards:

1. {index\_name}/{shard\_id} only exists in 1 out of 7 data nodes. It should  
exist in 2 out of 7 data nodes since we have 1 replica setting.
2. For {index\_name}/{shard\_id} which exists in one of the data nodes,  
{index\_name}/{shard\_id}/\_state directory is missing
3. For {index\_name}/{shard\_id} which exists in one of the data nodes,  
{index\_name}/{shard\_id}/index directory has 0 files -\> all index files are  
missing.

I am able to simulate this scenario after _a few rounds of stopping and  
starting_ the ElasticSearch cluster nodes (a few nodes at a time).  
Is this a known issue that {index\_name}/{shard\_id}/\_state directory and the  
index files will be lost if the nodes are restarted during  
initializing/relocating?

Thanks.

Lee Chuen
