Hi,

please try this workaround, replace the following line in
/usr/lib/python3.6/site-packages/vdsm/gluster/cli.py


value['stripeCount'] = el.find('stripeCount').text


with:

if (el.find('stripeCount')): value['stripeCount'] =
el.find('stripeCount').text


Then restart vdsmd and supervdmsd and retry. It worked for me, and it
looks like a serious bug for people upgrading to glusterfs 10.

Cheers,


     Alessandro
