Следующая роль установит nfs сервер и настроит клиентов.
Нужно будет только поправить файл hosts и в /etc/ansible/playbooks/roles_play/nfs.yml указать пути до директорий на мастере и слейве.

Здесь:
dir_nfs_master - директория на мастер сервере к которой будут подключаться клиенты
dir_nfs_client - директория на слейвах, в неё будет монтироваться директория с мастер сервера.
