Hello,

I have a 3 node ES cluster. Sometimes I do restarts on some or all of the nodes. Despite disabling shard allocation as explained [here](https://www.elastic.co/guide/en/elasticsearch/reference/7.17/rolling-upgrades.html#_upgrading_your_cluster), I still get failed shards after the restart is complete and shard re-allocation enabled.  
I assume the process (Allocation, re-allocation) is complete when I get code 200, or acknowledge: true

When you expand, this is what I get

Thanks for reaching out, @tegerei.

[This guide](https://www.elastic.co/guide/en/elasticsearch/reference/current/restart-cluster.html) might be a good starting point. This older [post](https://discuss.elastic.co/t/shards-unassigned-after-node-restarts-reason-node-left/67489) may be helpful too.

Best,  
Jessica

Thanks. I was making mistakes. I disabled shard allocation once in a rolling restart.
