You typically see these errors on shards that experienced running out of disk space in the past. Once index get corrupted like this, you will be getting these error messages on every attempt to merge segments. I would try to make a copy of the index and run CheckIndex[https://github.com/elasticsearch/elasticsearch/pull/1890](https://github.com/elasticsearch/elasticsearch/pull/1890)on it.
