The image is just striped across RADOS objects. In general you can think of it behaving exactly like a hard drive connected to your computer over iSCSI — a proper shared FS (eg, OCFS2) will work on top of it, but there's no magic that makes running an ext4 mount on two machines work... -Greg Software Engineer #42 @ http://inktank.com | http://ceph.com _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
