Seems Ceph has the vm-112-disk-0 still stored somewhere. At least this
error message should be visible in the ceph logs. Hopefully there is
more info about it.

Does the 'rbd showmapped' show the image being mapped? Are you running
filestore or bluestore OSDs?

If you migrate the VM to a different host, does it occure there too?
