We had some discussion at the office about restarting a node or service when there is 1 node only issue.
Some people find that it is a bit awkwark to follow the step from "Full-cluster restart" documentation for only one node. Just to be clear here, we are not restarting all nodes. But following the step 1 ( Disable shard allocation.) and 2 ( Stop indexing and perform a synced flush) and restart ONLY the node with issue. Not all of them.
We are using version 7.13.4.
Is somebody can confirm that we have to follow these step, or not, and why ?
