GitHub user jrmy911 closed a discussion: Moving shards
I found the documentation about [moving shards](https://docs.couchdb.org/en/stable/cluster/sharding.html) and got through the first steps by enabling maintenance mode. I haven't got a ton of experience with JSON but I was wondering how I could update the changelog, by_node and by_range. I feel like the documentation "skips" the CLI for this: `To add a shard to a node, add entries like this to the database metadata’s changelog attribute: ["add", "{range}", "{node-name}"]` It goes rather quick on how about to add that fourth node, if using the example in the documentation. Okay, but how does this translate into a CLI command using `curl -X PUT -H "Content-type: application/json"` ? That's where my knowledge is limited. I tried different things like: `curl -X PUT -H "Content-type: application/json" http://{hostname}/_node/_local/_dbs/{dbname} -d '["add","{range}","{node-name}"]'` `curl -X PUT -H "Content-type: application/json" http://{hostname}/_node/_local/_dbs/{dbname} -d '["add",{range},{node-name}]'` But it eventually fails and it is either invalid JSON or `{"error":"bad_request","reason":"Document must be a JSON object"}`. I'm sure I'm not entirely using the correct syntax, but after having gone through CouchDB's documentation (and the JSON API page), I am feeling a bit lost. :) GitHub link: https://github.com/apache/couchdb/discussions/4544 ---- This is an automatically sent email for [email protected].
