Install and configure components

yum install openstack-cinder

/etc/cinder/cinder.conf

su -s /bin/sh -c "cinder-manage db sync" cinder

Configure Compute to use Block Storage

/etc/nova/nova.conf

[cinder]os_region_name = RegionOne

Finalize installation

systemctl restart openstack-nova-api.servicesystemctl enable openstack-cinder-api.service openstack-cinder-scheduler.servicesystemctl start openstack-cinder-api.service openstack-cinder-scheduler.service

2.Install and configure a storage node

Prerequisites

yum install lvm2systemctl enable lvm2-lvmetad.servicesystemctl start lvm2-lvmetad.servicepvcreate /dev/sdbvgcreate cinder-volumes /dev/sdb

/etc/lvm/lvm.conf

devices {...filter = [ "a/sdb/", "r/.*/"]
