Hi
I have a elasticsearch service running on one node. After I restart the ES. Some shard remain unassigned.
```
[sflow@ES01 bin]$ curl -XGET 'ES01:9200/_cat/shards?pretty'

Below are the logs. I removed some line to make it short

What does `_cat/recovery` show?

Hi Warkolm
I think it is no longer a problem now.
The situation only happen when I import a lot of data into elasticsearch.
After index a lot data into es, the es shards will remain in a state (we can call it state unmerged I think) for a while.
During that time if I kill the es and restart the es, the shards will need some time to recovery.
So it will back to ok after a few min

Transaction log replay, probably.
