I'm looking at \_cat/recovery stats.

I have 7 shards marked as relocating, but it seems that only 1 shard at a time is relocated.

Every time I run \_cat/recovery 6 shards are at 0.1% while 1 slowly grows until completed and then another one starts.

Take a look at [https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-indices.html#recovery](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-indices.html#recovery)
