初始化cinder数据库

su -s /bin/sh -c "cinder-manage db sync" cinder && mysql -ucinder -pcinder -e "use cinder; show tables;"

cat /etc/nova/nova.conf (增加)

[cinder]
os_region_name = RegionOne
systemctl restart openstack-nova-api openstack-cinder-api openstack-cinder-scheduler
systemctl enable openstack-cinder-api openstack-cinder-scheduler

 

创建服务与端点

openstack service create --name cinder --description "Openstack Block Storage" volumev2
openstack service create --name cinder --description "Openstack Block Storage" volumev3

openstack endpoint create --region RegionOne volumev2 public http://192.168.3.220:8776/v2/%(tenant_id)s
openstack endpoint create --region RegionOne volumev2 internal http://192.168.3.220:8776/v2/%(tenant_id)s
openstack endpoint create --region RegionOne volumev2 admin http://192.168.3.220:8776/v2/%(tenant_id)s

openstack endpoint create --region RegionOne volumev3 public http://192.168.3.220:8776/v3/%(tenant_id)s
openstack endpoint create --region RegionOne volumev3 internal http://192.168.3.220:8776/v3/%(tenant_id)s
openstack endpoint create --region RegionOne volumev3 admin http://192.168.3.220:8776/v3/%(tenant_id)s

LVM节点（这里配置在控制器上）

安装并设置卡机启动

yum install -y lvm2 targetcli python-keystone openstack-cinder
systemctl enable lvm2-lvmetad && systemctl start lvm2-lvmetad

配置lvm卷

fdisk -l
pvcreate /dev/sdb
vgcreate cinder-volumes /dev/sdb (查看vgdisplay cinder-volumes )

vim /etc/lvm/lvm.conf （中）{    sed -i 's#^devices {#& filter = [ "a/sda/", "a/sdb/", "r/.*/"]#g'  /etc/lvm/lvm.conf             }
devices { (系统又lvm才这样操作，排除掉系统本身的lvm，控制器上也需要配)
......
filter = [ "a/sda/", "a/sdb/", "r/.*/"]（存储节点，在控制器上需要配）
}

/etc/cinder/cinder.conf 增加

[DEFAULT]
verbose = True
enabled_backends = lvm
glance_host = http://192.168.3.220:9292

[lvm]
volume_driver = cinder.volume.drivers.lvm.LVMVolumeDriver
volume_group = cinder-volumes
iscsi_protocol = iscsi
iscsi_helper = lioadm

[backend_defaults]
iscsci_ip_address = 192.168.3.220

重启服务

systemctl enable openstack-cinder-volume target && systemctl restart openstack-cinder-volume target

控制器查看卷
