What happened was "images" had way too many PGs, so I flattened all of the rbds in "volumes", copied over to a new "images" pool and then deleted the old one. When I flattened the volumes, the snapshots remained associated with the original parent (is this a bug/limitation/expected...?). I didn't mind just deleting the snapshots bc I assumed they were borked. However with this particular snapshot "$SNAP", this thing happened where the metadata broke and I can't unprotected it. > The rbd_children and rbd_directory objects store state as omap key/values, > not as actual binary data within the object. You can use "rados -p rbd > listomapvals rbd_directory/rbd_children" to see the data within the files. > Ah, thanks for the info. I guess I need to use rmomapkey on rbd_children. _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
