Restarting your TripleO hypervisor will break cinder volume service thus the overcloud pingtest
Tags: tripleo, openstack October 30, 2017
I don’t usualy restart my hypervisor, today I had to install LVM2 and virsh stopped to work so a restart was required, once the VMs were up and running the overcloud pingtest failed as cinder was not able to start.
From your Overcloud controller run:
sudo losetup -f /var/lib/cinder/cinder-volumes sudo vgdisplay sudo service openstack-cinder-volume restart
This will make your Overcloud pingtest work again.
