My snapshot repo has filled up and I don't seem to be able to force delete any old snapshots.
When I try to delete an old snapshot, I get this:
{
   "error": {
      "root_cause": [
         {
            "type": "repository_exception",
            "reason": "[tmp] failed to update snapshot in repository"
         }
      ],
      "type": "repository_exception",
      "reason": "[tmp] failed to update snapshot in repository",
      "caused_by": {
         "type": "file_system_exception",
         "reason": "/elasticsearch/backups/tmp/pending-index-8371-7Pcd70vUSk2d8wsvLAfzfg: No space left on device"
      }
   },
   "status": 500
}
I know I could go into the FS and delete the files, which I've done in the past - but I'd imagine there must be some way to force a delete from the API
EDIT: Version 5.2.0, 5 nodes, all data on running on CentOS 7 - using an NFS share as the repo.
