Should I do something like this? (below, after stop osd.36)
# ceph-objectstore-tool --data-path /var/lib/ceph/osd/ceph-36/ --journal-path /dev/sdc1 rbd_data.dfd5e2235befd0.000000000001c299 remove-clone-metadata 326022
I'm no sure about rbd_data.$RBD and $CLONEID (took from rados
list-inconsistent-obj, also below).
