Re: [Users] vdsm python error

I am attempting to use vdsm with arch linux and I am getting this error when I run vdsm-tool Traceback (most recent call last): File "/usr/bin/vdsm-tool", line 151, in main return tool_command[cmd]["command"](*args[1:]) File "/usr/lib/python2.7/site-packages/vdsm/tool/configurator.py", line 220, in configure if service.service_status(s, False) == 0: File "/usr/lib/python2.7/site-packages/vdsm/tool/service.py", line 378, in service_status return _runAlts(_srvStatusAlts, srvName) File "/usr/lib/python2.7/site-packages/vdsm/tool/service.py", line 341, in _runAlts rc, out, err = alt(srv, *args, **kwarg) File "/usr/lib/python2.7/site-packages/vdsm/tool/service.py", line 110, in wrapper rc, out, err = execCmd(cmd, raw=False) File "/usr/lib/python2.7/site-packages/vdsm/tool/service.py", line 36, in execCmd return _execCmd(argv, raw=raw, *args, **kwargs) File "/usr/lib/python2.7/site-packages/vdsm/utils.py", line 682, in execCmd deathSignal=deathSignal, childUmask=childUmask) TypeError: __init__() got an unexpected keyword argument 'childUmask' How I can solve it ?
