I followed the instructions, but it seems that 'rados -p rbd ls | grep
'^rbd_data.221bf2eb141f2.' | xargs -n 200  rados -p rbd rm' gets stuck,
too. It's running since Friday and still not finished. The rbd image
is/was about 1 TB large.

Until now the only output was:
error removing rbd>rbd_data.221bf2eb141f2.00000000000051d2: (2) No such
file or directory
error removing rbd>rbd_data.221bf2eb141f2.000000000000e3f2: (2) No such
file or directory
