As I understand it: 4.2G is used by ceph (all replication, metadata, et al) it is a sum of all the space "used" on the osds. 958M is the actual space the data in cephfs is using (without replication). 3.8G means you have some sparse files in cephfs. 'ceph df detail' should return something close to 958MB used for your cephfs "data" pool. "RAW USED" should be close to 4.2GB -- Adam On Sun, Jan 17, 2016 at 9:53 PM, Francois Lafont <flafdivers@xxxxxxx> wrote: > On 18/01/2016 04:19, Francois Lafont wrote: > >> ~# du -sh /mnt/cephfs >> 958M /mnt/cephfs >> >> ~# df -h /mnt/cephfs/ >> Filesystem Size Used Avail Use% Mounted on >> ceph-fuse 55T 4.2G 55T 1% /mnt/cephfs > > Even with the option --apparent-size, the size are different (but closer indeed): > > ~# du -sh --apparent-size /mnt/cephfs > 3.8G /mnt/cephfs > > > -- > François Lafont > _______________________________________________ > ceph-users mailing list > ceph-users@xxxxxxxxxxxxxx > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
