I am using an ES cluster (2 clients, 5 data nodes, 3 master nodes) with mounted volumes to NFS...
When I delete old indices (using sense) I see they are actually deleted, but after I restart the ES cluster, I see that the old indices come back again with red status and the explain API says something like: "unassigned_shards exist in the cluster state, but cannot be found in the cluster itself"
