Hi, Today we had a big crash in our Netapp cabinet and our elastic cluster went down  
After starting up all our indices appeared to be ok with the exception of this internal's elasticsearch index `.async-search`  
which is in red state.  
I have not problems running normal searches but I'm no able to use discovery/visualizations/etc (I suposse kibana uses async\_search)  
(below the cluster allocation explain)

```auto
