Although the RBD disk can be shared, that will only be useful if the file system you put on top is designed to allow that. The usual suspects (ext4, xfs, etc.) do not--they assume only a single host is using the disk at any time. That means that unless you deploy a cluster fs like ocfs2 or gfs2, you can only use an RBD on a single host at a time. sage _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
