Hi, This mail is for the search engines. An old "Won't Fix" ticket is still quite relevant: http://tracker.ceph.com/issues/16211 When you upgrade an old rbd cluster to luminous, there is a good chance you will have several rbd images with unreadable header objects. E.g. # rbd info -p volumes volume-d865f046-6f0e-4a95-9e2f-9d228af8c3ef 2018-07-17 18:15:57.224508 7fdf5a7fc700 -1 librbd::image::OpenRequest: failed to retreive immutable metadata: (2) No such file or directory rbd: error opening image volume-d865f046-6f0e-4a95-9e2f-9d228af8c3ef: (2) No such file or directory The workaround is to set a dummy omap key on the header object -- Wido provided a script to do this in the tracker issue above.
