Hi all, I'm trying to get the real disk usage of a Cinder volume converting this bash commands to python: http://cephnotes.ksperis.com/blog/2013/08/28/rbd-image-real-size
I wrote a small test function which has already worked in many cases but it stops with a core dump while trying to calculate the real size of a particular volume. This is the function: http://paste.openstack.org/show/477563/ this is the error I get: http://paste.openstack.org/show/477567/ and these are the related rbd info: http://paste.openstack.org/show/477568/ Can anyone help me to debug the problem? Thanks Giuseppe
