RBD volumes don't live on a given host in the cluster; they are striped across all of them.

This sounds like maybe you don't have quite the same configuration on both hosts. Due to the way OpenStack and virsh handle their config fragments and secrets, you need to have the same virsh secret-IDs both configured (in the OpenStack config files) and set (in virsh's internal database) on every compute host and the Cinder/Nova manager. -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
