Well, when you upgrade from one major version to another, you will always have a certain amount of time when half the cluster is running one major and the other half is running another version, so that is meant to work, even if it might be unwise to run like that for a very long time. -- May the most significant bit of your life be positive. _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
