Hallo Dieter, Kein Fehler, sondern ein fehlendes Kommando. Ein neuer pool muss dem mds erst bekannt gemacht werden. ceph mds add_data_pool <pool number> Siehe Mitschnitt unten. Damit duerfte uebrigens auch meine Frage von gestern geloest sein: die zugehoerigkeit zu einem bestimmten Pool kann fuer ein Verzeichnis und damit einen ganzen Baum vergeben werden.
