When you run df against a CephFS mount, it generally reports the same data as you get out of RADOS — so if you have replica 2 and 4 TB of data, it will report as 8TB used (since, after all, you have used 8TB!). There are exceptions in a few cases; you can have it based off of your quotas for subtree mounts for one. -Greg _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
