Good day,
for some reason my shards are showing up in my cluster as UNASSIGNED NODE\_LEFT. i wrote a script based on recommendation on the web. however it doe not relocate the shards... please help

Did a node leave?

That is probably not the best.

The node that had the shards that are unassigned now has crashed / was shut down and there is no other node with that data (as you didn't configure replicas). If you don't care about the data, feel free to delete the indices.

It looks to me in 5.0 the cluster reroute command changed and no longer accepts the "allocate" parameter. That would explain this error.
From the documentation for cluster/reroute in previous versions of ES:
> 'allocate'
> Allocate an unassigned shard to a node. Accepts the index and shard for index name and shard number, and node to allocate the shard to. It also accepts allow\_primary flag to explicitly specify that it is allowed to explicitly allocate a primary shard (might result in data loss).
Do you see something else that indicates the data is missing altogether?
