部署cinder

1. 部署说明

部署地点： 控制节点（ip:192.168.0.142)。

2. 创建一个lvm的分区

storage node (没有存储节点,使用controller上的存储 )。

在选定磁盘上创建一个lvm的分区。

fdisk /dev/sba
fdisk -l

输出信息：

#Disk /dev/sda
#设备             起点       末尾       扇区  大小 类型
#/dev/sda1        2048 3400000000 3399997953  1.6T Linux 文件系统
#/dev/sda2  3400001536 7812939742 4412938207  2.1T Linux LVM

3. 安装软件包

yum install -y lvm2 device-mapper-persistent-data

4. 启动lvm2-lvmetad服务

systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service

创建 LVM 物理卷 /dev/sda2：

pvcreate /dev/sda2

创建 LVM 卷组 cinder-volumes。

vgcreate cinder-volumes /dev/sda2

5. 编辑/etc/lvm/lvm.conf

在设备部分，添加一个过滤器，接受 /dev/sda2 设备，拒绝所有其他设备。

devices {
...
filter = [ "a/sda2/", "r/.*/"]

6. 安装cinder

yum install -y openstack-cinder targetcli

7. 创建cinder数据库

mysql -uroot -ploongson -e 'CREATE DATABASE cinder;'
mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'loongson';"
mysql -uroot -ploongson -e "GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'loongson';"

创建服务证书并输入密码 loongson。

openstack user create --domain default --password-prompt cinder

为cinder用户添加管理员角色：

openstack role add --project service --user cinder admin

创建 cinderv2 和 cinderv3 服务实体：

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2
openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

创建块存储服务 API 端点：

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 internal http://controller:8776/v3/%\(project_id\)s
openstack endpoint create --region RegionOne   volumev3 admin http://controller:8776/v3/%\(project_id\)s

crudini --set /etc/cinder/cinder.conf lvm target_helper  lioadm
crudini --set /etc/cinder/cinder.conf lvm volume_backend_name LVM

填充块存储数据库。

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

egrep -v "^#|^$" /etc/cinder/cinder.conf

crudini --set /etc/nova/nova.conf cinder os_region_name  RegionOne
systemctl restart openstack-nova-api.service

systemctl enable openstack-cinder-volume.service target.service openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl restart openstack-cinder-volume.service target.service openstack-cinder-api.service openstack-cinder-scheduler.service
systemctl status openstack-cinder-volume.service target.service openstack-cinder-api.service openstack-cinder-scheduler.service

创建一个volume type并关联到volume_backend_name。

cinder type-create LVM
cinder type-key LVM set volume_backend_name=LVM
cinder extra-specs-list
