Hi Dan,
I sent a patch for vdsm to get the gluster volume capacity statistics using libgf api ( patch : http://gerrit.ovirt.org/#/c/26343 ), This patch requires glusterfs-devel package for build.
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@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 (such as an independent python-glfs package)?

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, Darshan N

I hope Toni can help out here, he found outr that when using threads, you must declare the function prototype explicitly, but I'm not at all sure this is your issue.

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..
