As they are unassigned, Elasticsearch does not know the size, so that is natural. Monitor the number of assigned/unassigned shards and see if this changes over time.

As you potentially have had a network partition and tried to resolve the issue during this you may have suffered data loss. If closing and reopening indices does not work it may be necessary to delete them and restore from a backup (I saw that you have the `repository-s3` plugin installed).
