OpenStack Train版-14.安装块存储服务cinder（存储节点）

安装cinder块存储服务节点(存储节点192.168.0.40)
使用默认的LVM卷方法，之后改为ceph存储

安装LVM软件包

[root@cinder01 ~]# yum install lvm2 device-mapper-persistent-data -y

启动LVM元数据服务，并设置开机自启

systemctl enable lvm2-lvmetad.service
systemctl restart lvm2-lvmetad.service

添加一块100G硬盘，重启节点后创建LVM物理卷/dev/sdb

[root@cinder01 ~]# pvcreate /dev/sdb
Physical volume "/dev/sdb" successfully created.

创建LVM物理卷

[root@cinder01 ~]# vgcreate cinder-volumes /dev/sdb
Volume group "cinder-volumes" successfully created

编辑配置文件/etc/lvm/lvm.conf

在devices部分，添加一个过滤器，只接受/dev/sdb设备，拒绝其他所有设备

[root@cinder01 ~]# vim /etc/lvm/lvm.conf
devices {
filter = [ "a/sdb/", "r/.*/" ]

安装train版yum源和cinder软件包

yum install centos-release-openstack-train -y
yum install openstack-cinder targetcli python-keystone openstack-utils -y

编辑配置文件/etc/cinder/cinder.conf

cp /etc/cinder/cinder.conf /etc/cinder/cinder.conf.bak
grep -Ev '#|^$' /etc/cinder/cinder.conf.bak>/etc/cinder/cinder.conf

openstack-config --set /etc/cinder/cinder.conf lvm target_helper lioadm
openstack-config --set /etc/cinder/cinder.conf oslo_concurrency lock_path /var/lib/cinder/tmp

启动块存储卷服务并设置开机自启动

systemctl restart openstack-cinder-volume.service target.service
systemctl enable openstack-cinder-volume.service target.service

在控制节点进行验证

[root@controller ~]# source ~/admin-openrc
[root@controller ~]# openstack volume service list
