Hello list, I upgraded to mimic some time ago and want to make use of the upmap feature now. But I can't do "ceph osd set-require-min-compat-client luminous" as there are still pre-luminous clients connected. The cluster was originally created from jewel release. When I run "ceph features", I see many connections from jewel clients though all systems have mimic installed and are rebooted since then. 08:44 dk@mon03 [fra]:~$ ceph features [...] "client": [ { "features": "0x7010fb86aa42ada", "release": "jewel", "num": 70 }, { "features": "0x3ffddff8eea4fffb", "release": "luminous", "num": 185 }, { "features": "0x3ffddff8ffa4fffb", "release": "luminous", "num": 403 } [...] These client connections belong to mapped rbd images. When I inspect the rbd images with "rbd info" I don't see any difference in format and features. How can I determine which rbd images are affected and how can I transform them to luminous types if possible. Thanks, Denny _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
