Please, do we have to setup a curator on all nodes of the cluster (each node is on a server) ?

No. Only one instance is necessary, and it doesn’t have to be on a cluster node. It can be anywhere that has access to an http/https port in the cluster.

I don't know why Elasticsearch doesn't want to load :

```auto

This could be for a couple of reasons.

1. One of your indices is big enough that its shards overwhelmed one box.
2. You had one or more nodes fail, and Elasticsearch tried to promote primaries on the remaining boxes, filling them.
3. Your nodes are not (or are no longer) clustered properly (a split-brain scenario perhaps), so a delete to one node did not propagate across the entire cluster.
4. Something I haven't listed here.

If you're full, there's not much I can do to help. You'll have to delete some or all of what's in the `/data` path. Hopefully you can restore from a snapshot.
