Rob,

It seems that a bug in vdsm code is hiding the real issue.
Could you do a

    sed -i s/ParseError/ElementTree.ParseError /usr/share/vdsm/gluster/cli.py

restart vdsmd, and retry?

Bala, would you send a patch fixing the ParseError issue (and adding a
unit test that would have caught it on time)?


Regards,
Dan.
