Hi, We want to enable the hammer rbd features on newly created Cinder volumes [1], but we still have a few VMs running with super old librbd running (dumpling). Perhaps its academic, but does anyone know the expected behaviour if an old dumpling-linked qemu-kvm tries to attach an rbd with exclusive-lock+objectmap enabled? I hope it will just refuse to attach, rather than attach but allow bad stuff to happen. Thanks in advance! Dan [1] By adding rbd default format = 2 rbd default features = 13 to our client side ceph.conf. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
