I have see many such failures today, here is 2 bulids - both on same slave (slave issue?)

   https://jenkins.ovirt.org/blue/organizations/jenkins/vdsm_standard-check-patch/detail/vdsm_standard-check-patch/6511/pipeline

2. [2019-06-20T22:20:50.288Z] Running on node: vm0015.workers-phx.ovirt.org (el7 phx nested local_disk)

   https://jenkins.ovirt.org/blue/organizations/jenkins/vdsm_standard-check-patch/detail/vdsm_standard-check-patch/6509/pipeline

Looks like there was no build on this slave in the last 2 days:

The failure looks like this:
