Hi,

I am trying to create a Ceph block device on a ceph cluster machine itself for 
experimental purposes. I used to be able to do that earlier but it gives me a 
segmentation fault right now:

Could anybody help me out here? I have no issues creating an image on a 
separate client machine.

Thanks,
