You could construct the information by listing al the objects in each pool and calculating if they live on the OSD in question, but there is not an interface to have an OSD go list its contents. >Ok. >> 3.

There is not special handling for multiple reads from the same OSD, if that's what you're asking. > i meant in time factor. Take the following sinario if we notice that certain client always or let say more frequent need to open to objects n these two were in different osd would it better to make those objects be in the same osd? > -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
