I found way to delete it but you need to check object location (pg and osd) and then after stopping osd manualy remove it from all osd. After this you will have inconsistent pg but you can fix this by repairing pg. I'm not sure if this is good way of fixing this problem. In my case I'm looking for other solution which will be faster ( removing 1 object was taking about 1-2min per osd on hdd drive) Best regards Bartosz Skotnicki ________________________________ Od: James, GleSYS <james.mcewan(a)glesys.se> Wysłane: piątek, 29 stycznia 2021 08:45:24 Do: ceph-users Temat: [ceph-users] Can see objects with "rados ls" but cannot delete them with "rados rm" Hi, We have in issue in our cluster (octopus 15.2.7) where we’re unable to remove orphaned objects from a pool, despite the fact these objects can be listed with “rados ls”. Here is an example of an orphaned object which we can list (not sure why multiple objects are returned with the same name…related to the issue perhaps?) rados ls -p default.rgw.buckets.data | grep -i 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 And the error message when we try to stat / rm the object: rados stat -p default.rgw.buckets.data 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 error stat-ing default.rgw.buckets.data/5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6: (2) No such file or directory rados -p default.rgw.buckets.data rm 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6 error removing default.rgw.buckets.data>5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83__shadow_anon_backup_xxxx_xx_xx_090109_7812500.bak.vLHmbxS4DAnRMDVjBYG-5X6iSmepDD6: (2) No such file or directory The bucket with id "5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83” was deleted from radosgw a few months ago, but we still have approximately 450,000 objects with this bucket id that are orphaned: cat orphan-list-202101191211.out | grep -i 5a5c812a-3d31-xxxx-xxxx-xxxxxxxxxxxx.4811659.83 | wc -l 448683 I can also see from our metrics that prior to deletion there was about 10TB of compressed data stored in this bucket, and this has not been reclaimed in the pool usage after the bucket was deleted. Anyone have any suggestions on how we can remove these objects and reclaim the space? We’re not using snapshots or cache tiers in our environment.
