Create database for cinder services
CREATE DATABASE cinder;
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'password';
FLUSH PRIVILEGES;
exit
Create service credentials
. admin-openrc
openstack user create --domain default --password-prompt cinder
openstack role add --project homelab --user cinder admin
Create the cinderv2 and cinderv3 service entities
openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3
Create service endpoints
openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s
openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s

openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s
Install the packages
apt install -y cinder-api cinder-scheduler
Update or update configurations in respective sections as shown below in /etc/cinder/cinder.conf
[database]
connection = mysql+pymysql://cinder:password@controller/cinder
[DEFAULT]
transport_url = rabbit://openstack:password@controller
auth_strategy = keystone
my_ip = 10.99.1.3
Add the following sections in /etc/cinder/cinder.conf
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = homelab
username = cinder
password = password
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp
Populate the database
su -s /bin/sh -c "cinder-manage db sync" cinder
Update cinder section in /etc/nova/nova.conf
[cinder]
os_region_name = RegionOne
Restart impacted services
service nova-api restart
service cinder-scheduler restart service apache2 restart
Create Cinder Volumes
Install required supporting packages
apt install -y lvm2 thin-provisioning-tools
I had planned to use /dev/sdb for Cinder storage – Create the LVM physical volume /dev/sdb
pvcreate /dev/sdb
Note the above command failed as a partition was already created. I had used the following command to clear it and then proceed with pvcreate.
# wipefs -a /dev/sdb
/dev/sdb: 8 bytes were erased at offset 0x00000200 (gpt): 45 46 49 20 50 41 52 54
/dev/sdb: 8 bytes were erased at offset 0x2800cacfe00 (gpt): 45 46 49 20 50 41 52 54
/dev/sdb: 2 bytes were erased at offset 0x000001fe (PMBR): 55 aa
/dev/sdb: calling ioctl to re-read partition table: Success
# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created.
Create the LVM volume group cinder-volumes
vgcreate cinder-volumes /dev/sdb
Edit the /etc/lvm/lvm.conf file, in the devices section, add a filter that accepts the /dev/sdb device and rejects all other devices
devices { ... filter = [ "a/sdb/", "r/.*/"]
...
}
Install cinder-volume package
apt install -y cinder-volume
Update Glance API server configuration in the [DEFAULT] section of /etc/cinder/cinder.conf
[DEFAULT]
glance_api_servers = http://controller:9292
Add the following section to /etc/cinder/cinder.conf
[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
target_protocol = iscsi
target_helper = tgtadm
Restart services as listed below
service tgt restart
service cinder-volume restart
