Hi, short : I removed a 1TB RBD image, but I still see files about it on OSD. long : 1) I did : "rbd snap purge $pool/$img" but since it overload the cluster, I stopped it (CTRL+C) 2) latter, "rbd snap purge $pool/$img" 3) then, "rbd rm $pool/$img" now, on the disk I can found files of this v1 RBD image (prefix was rb.0.14bfb5a.238e1f29) : # find /var/lib/ceph/osd/ceph-64/ -name 'rb.0.14bfb5a.238e1f29.*' /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_3/rb.0.14bfb5a.238e1f29.000000021431__snapdir_C96635C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_3/rb.0.14bfb5a.238e1f29.000000005622__a252_32F435C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_3/rb.0.14bfb5a.238e1f29.000000021431__a252_C96635C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_3/rb.0.14bfb5a.238e1f29.000000005622__snapdir_32F435C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_9/rb.0.14bfb5a.238e1f29.000000011e08__a172_594495C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_9/rb.0.14bfb5a.238e1f29.000000011e08__snapdir_594495C1__9 /var/lib/ceph/osd/ceph-64/current/9.5c1_head/DIR_1/DIR_C/DIR_5/DIR_A/rb.0.14bfb5a.238e1f29.000000021620__a252_779FA5C1__9 ... So, is there a way to force OSD to detect if files are orphans, then remove them ? Thanks, Olivier
