It looks like the libvirt (2.0.0-10.el7_3.2) that ships with centos 7.3 is broken out of the box when it comes to hot plugging new virtio-scsi devices backed by rbd and cephx auth. If you use openstack, cephx auth, and centos, I’d caution against the upgrade to centos 7.3 right now. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
