Right now you can only have a single filesystem per cluster, and there are sadly no controls to forcibly separate users in the tree. You *can* mount only a subtree of the full filesystem, and if you control root on the mounting nodes this might be sufficient. (We've also done some scoping work on securing this for a community blueprint in the Dumpling CDS, but unfortunately it wasn't picked up: http://wiki.ceph.com/01Planning/02Blueprints/Dumpling/Client_Security_for_CephFS.) You can also segregate the file data into different RADOS pools and restrict access to those pools on a per-client basis, but that leaves everybody's metadata visible to and subject to manipulation by the others. -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
