Hey hey hey :) i have found :) Stupid and in the same time weird :) Ok i have to many node test to manage them one by one, so i use pssh, pssh is tool to send same command to multiple server with ssh :) BUT pssh send install command to all my server in the same time :) I think database just have "little" problem when i do that :) So pssh is bad idea to deploy node with netmaker :)
