The nature of the program is that it is "prepped" by one-set of commands and queried by another, thus the RW case is extremely unlikely. I can change permission bits to rewoke the w-bit for the user, they dont need it anyway... it is just the same service-users that generates the data and queries it today. Can ceph tell the actual amount of clients? .. We have 55-60 hosts, where most of them mounts the catalog. -- Jesper _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
