Hi All, We have a single node elasticsearch having good amount of storage. It has been working fine since last one year and suddenly stopped working, seems due to data corruption. I can see few indices, for which state is in red by using api : https:///\_cat/indices I have few questions: Have all the red status indices corrupted or few of the indices are causing issue? Is there a way to identify the corrupt indices and can these be fixed? Regards, Neeraj Bhagat ---

If you have a single node and no replicas any data in corrupt shards is probably lost. ---
