Do you see the objects lists when you do 'rados -p rbd ls - | grep <prefix>'? If the objects really are orphaned, teh way to clean them up is via 'rados -p rbd rm <objectname>'. I'd like to get to the bottom of how they ended up that way first, though! sage > > Thanks for any advice, > Olivier > > PS : not sure if this kind of problem is for the user or dev mailing > list. > > Le mardi 20 mai 2014 ? 11:32 +0200, Olivier Bonvalet a ?crit : > > 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 > > > > _______________________________________________ > > ceph-users mailing list > > ceph-users at lists.ceph.com > > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > > > > -- > To unsubscribe from this list: send the line "unsubscribe ceph-devel" in > the body of a message to majordomo at vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > >
