The disk threshold stuff has been available since sometime in 0.90. In 1.3 it'll be on by default. It works by stopping allocation to shards with disks over a watermark and moving shards off nodes that are over another higher mark. Meaning elasticsearch won't try to balance usage. Just keep from filling up disk. It's a somewhat fine distinction but a real one. On Jun 12, 2014 6:37 PM, "Mark Walkom" <[email protected]> wrote:
