Maybe you should pass it with quotes -> vdsClient 0 glusterVolumeSizeInfoGet volumeName="gv1" But probably that's not the issue, Did you try to add prints in http://gerrit.ovirt.org/#/c/17822/5/client/vdsClientGluster.py to see where the segfault is raised exactly ? still, if you prefer to debug step by step you can use any remote debuger (as pycharm) and in this case its easy, as it only one process and direct flow to step on. You need to check the all flow and not only the last call (gfapi.volumeStatvfs("gv1")) If you sure it raises inside the gfapi call with the same "gv1" as input, let me know and I'll investigate more

Hi,
In following patch I am using ctypes to load libgfapi(GlusterFS API) to get the Gluster volume statvfs information. http://gerrit.ovirt.org/#/c/17822
I am getting segfault when I run vdsClient 0 glusterVolumeSizeInfoGet volumeName=gv1
But I checked as below and it is working.
cd /usr/share/vdsm python
from gluster import gfapi print gfapi.volumeStatvfs("gv1")
posix.statvfs_result(f_bsize=4096L, f_frsize=4096L, f_blocks=25803070L, f_bfree=19130426L, f_bavail=17819706L, f_files=6553600L, f_ffree=5855876L, f_favail=5855876L, f_flag=4096L, f_namemax=255L)
Please suggest how I can debug this issue.
