Description

Setup required for the OpenStack Volumes. In the Folsom release of OpenStack, the nova-volume service was deprecated by the split out cinder service.


How to test

To create the cinder-volumes Volume Group for the openstack-cinder-volume service

sudo truncate -s20G /var/lib/cinder/cinder-volumes.img
sudo vgcreate cinder-volumes $(sudo losetup --show -f /var/lib/cinder/cinder-volumes.img)


Because the volume service is dependent on the volume group being available, it's not started by default, so to do that:

sudo systemctl start openstack-cinder-volume.service

Actions after each reboot

The above commands are not persistent across reboots, so please rerun these commands after reboot:

sudo losetup -f /var/lib/cinder/cinder-volumes.img
sudo systemctl start openstack-cinder-volume.service

If you intend to make them persist automatically, then enable the service to start in the standard manner, but ensure that the losetup is run early in the boot process, or instead, use an implicitly persistent block device/partition.

Temporary workaround for packaging issue

The config files in /etc/tgt/conf.d/ don't honor globbing. Only the main /etc/tgt/targets.conf seems to. So to avoid that issue causing tgtd to not start:

sudo sed -i 's/include/#include/' /etc/tgt/conf.d/{nova,cinder}.conf
sudo sed -i '1iinclude /etc/nova/volumes/*' /etc/tgt/targets.conf
sudo sed -i '1iinclude /etc/cinder/volumes/*' /etc/tgt/targets.conf

then restart tgtd:

sudo systemctl restart tgtd.service

Expected Results

Check the volume group is listed by this command

vgs

Check that no errors are reported in /var/log/cinder/* or by this command:

sudo systemctl status openstack-cinder-volume.service
