hey folks,

as we added an additional es node yesterday(actually an other instance of  
ES with an different data path on our server), some of the shards that were  
moved to this node, keep stuck initializing.

Given to the debug logs, it seems like they got corrupted during the copy  
process (about 20 of 140 moved shards got this problem...) so i decided it  
could help to manually assign them to an node, using the reroute-api.

=\> curl -X POST \

'[http://localhost:9200/\_cluster/reroute?pretty=true](http://localhost:9200/_cluster/reroute?pretty=true)' \

```
-d '{ "commands" : [ { "allocate" : { "index" : "logstash-2014.06.07", 

```

"shard" : 2 , "node" : "Storage", "allow\_primary" : 2 }}]}'

After I issued the command, ES tried to initialize the shard, but then this  
suddenly happend:

[https://lh6.googleusercontent.com/-RnP051vjz1I/VIqlJQLi4-I/AAAAAAAAADg/tC5q9TDr5HQ/s1600/sizeafter.PNG](https://lh6.googleusercontent.com/-RnP051vjz1I/VIqlJQLi4-I/AAAAAAAAADg/tC5q9TDr5HQ/s1600/sizeafter.PNG)

It seems like ES decided to delete the whole shard, due to its (potential)  
corruption and with it 1/3 of the data in it.

In my opinion ES should never ever be allowed to delete anything without  
permission, any clue what happened in this case?

Thanks for feedback
