After restarting the cluster due to some performance issues, we suddenly
had far fewer indices than before. They aren't closed or
recovering/unallocated, they just don't exist according to the API. The
data files still exist on our data nodes and I believe the data is still
there (we had 2 replicas per shard); it's just as if the cluster state was
corrupted somehow. Is there some way to recover or recreate this
state/metadata for the missing indices? We tried turning on verbose
recovery/gateway logging, but still saw no mention of them.
