I think you're running into that bug, someone mentioned the following which seemed to
work for my nodes that complained of not being able to connect to the storage pool.
The following fix worked for me, i.e. replacing the following line in
/usr/lib/python3.6/site-packages/vdsm/gluster/cli.y
Replace: value['stripeCount'] =el.find('stripeCount').text
With: if (el.find('stripeCount')): value['stripeCount'] =
el.find('stripeCount').text
Restart VSMD and SuperVSMD and then your host should be able to connect if you have the
same issue
