The use of this id is to recover state from a remote volume management facility so upon relocation, my nodes' data moves along with it.\r\n\r\nThis causes my application definitions to explode with duplicated data as cluster size grows ( and of course instead of scaling it, i need to re-launch the entire thing if using an application group, or just add additional applications when not )\r\n\r\ni understand this is probably not a trivial change.\r\nI also understand this is probably not the first time  the issue comes up and i apologize if i missed any existing issues on it.\r\n\r\n\r\nthanks,\r\nAndras\r\n\r\n"},"comment":{"url":"https://api.github.com/repos/mesosphere/marathon/issues/comments/190093667","html_url":"https://github.com/mesosphere/marathon/issues/2796#issuecomment-190093667","issue_url":"https://api.github.com/repos/mesosphere/marathon/issues/2796","id":190093667,"user":{"login":"wleese","id":2562645,"avatar_url":"https://avatars.githubusercontent.com/u/2562645?v=3","gravatar_id":"","url":"https://api.github.com/users/wleese","html_url":"https://github.com/wleese","followers_url":"https://api.github.com/users/wleese/followers","following_url":"https://api.github.com/users/wleese/following{/other_user}","gists_url":"https://api.github.com/users/wleese/gists{/gist_id}","starred_url":"https://api.github.com/users/wleese/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/wleese/subscriptions","organizations_url":"https://api.github.com/users/wleese/orgs","repos_url":"https://api.github.com/users/wleese/repos","events_url":"https://api.github.com/users/wleese/events{/privacy}","received_events_url":"https://api.github.com/users/wleese/received_events","type":"User","site_admin":false},"created_at":"2016-02-29T08:25:16Z","updated_at":"2016-02-29T08:25:16Z","body":"related to https://github.com/mesosphere/marathon/issues/1242"}}
