A cluster with masters with two slaves each\r\n2. Add a new node: `./redis-trib.rb add-node {new-node} {cluster-node}`\r\n3. Move some slots to the new-node\r\n\r\nThe new orphan node however is not assigned a slave from other masters as expected. I am not sure this is a feature or a bug in Redis Cluster or I miss something in my setup.\r\n\r\nI've tried another scenario which added a master with a slave and later failed the slave node. In this case, the orphan master was assigned a slave from another master, which was an expected behaviour from replication migration.\r\n\r\nThanks!"},"comment":{"url":"https://api.github.com/repos/antirez/redis/issues/comments/109100129","html_url":"https://github.com/antirez/redis/issues/2600#issuecomment-109100129","issue_url":"https://api.github.com/repos/antirez/redis/issues/2600","id":109100129,"user":{"login":"allanwax","id":8459774,"avatar_url":"https://avatars.githubusercontent.com/u/8459774?v=3","gravatar_id":"","url":"https://api.github.com/users/allanwax","html_url":"https://github.com/allanwax","followers_url":"https://api.github.com/users/allanwax/followers","following_url":"https://api.github.com/users/allanwax/following{/other_user}","gists_url":"https://api.github.com/users/allanwax/gists{/gist_id}","starred_url":"https://api.github.com/users/allanwax/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/allanwax/subscriptions","organizations_url":"https://api.github.com/users/allanwax/orgs","repos_url":"https://api.github.com/users/allanwax/repos","events_url":"https://api.github.com/users/allanwax/events{/privacy}","received_events_url":"https://api.github.com/users/allanwax/received_events","type":"User","site_admin":false},"created_at":"2015-06-05T00:06:51Z","updated_at":"2015-06-05T00:06:51Z","body":"Have you tried setting `cluster-migration-barrier 1` and retry the experiment to see what happens?\r\n"}}
