You can then use this block device as any other block device on your system: create a filesystem on it, use it as a raw block device, etc. $ rbd showmapped will give you the /dev/rbd<id> id. The other option is to use fuse. See documentation links below for details. http://ceph.com/docs/master/rbd/rbd-ko/ - rbd map http://ceph.com/docs/master/man/8/rbd-fuse/ - fuse http://ceph.com/docs/master/rbd/rbd/ - everything rbd Thanks, Ilya _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
