Hi Dan,
I sent a patch for vdsm to get the gluster volume capacity

It looks like jenkins does not have this package and so the build
for this patch is failing. Does jenkins automatically pull the required
package or is there anything to be done to get this package in jenkins ?.
Can you please help me to resolve this.
Generally speaking, if you want a new package installed, you should ask
that on infra(a)ovirt.org.
However, I am not at all happy with adding C code into Vdsm. What is it?
Python binding for glfs_statvfs ? Could this be implemented elsewhere

Hi,
We are making use of libgf-api for getting the statistics related
to a glusterfs volume, as it is more efficient than we mounting a volume
and getting the statistics.
libgfapi is a c api. Initially we tried using ctypes to wrap the
required functions in libgfapi. But because of a limitation in glusterfs
when these functions were invoked through supervdsm it would break.
So we thought of having an extension module that makes use of libgfapi
and provides the statistics, which can be used in vdsm.
what would be the better approach to resolve this ? Please provide us
your suggestions.
Thanks,

In my opionion, the python module that you suggest makes sense - but it
should be part of libgf - it is their's python binding (or part
thereof).

I have added glfs_statvfs in libgfapi python binding and its working ,
hopefully we can avoid all these issues via that.
Darshan, if we are getting any issue ( in vdsm ) even after using new
method, we will dig further..
